Redirecting to .aspx in a different domain - asp.net

Okay, I'm dealing with a problem hear.
I'm building landing pages for my company.
The main website works with a .aspx form to retrieve car data (from for example licenseplates).
Now we've set up some new relevant domain names to use for some of the landing pages.
The problem now is, that when on those pages I type in licenseplate and click search, it fails doing so.
Since it tries to find the .aspx form on the landing page domain url.
For example:
Main site: www.mysite.com/category.aspx?k=80zbfk (refered to when the licenseplate is typed in.)
Landing page: www.mysite2.com/category.aspx?k=80zbfk (were it refers to on the landing page)
No the second one should refer to the first one. But I can't seem to find a way to do so.
I don't have acces to the .aspx files since they're in control of a external company.
Is there any way to fix this? To refer the landing page to the .aspx from the main site?
Or do I have to contact the webcompany to ask for the files so I can copy them to the other domain?
Thanks in advance!

It sounds like you want to be using absolute links rather than relative.
An absolute link includes the host and path of the target url, whereas a relative one contains only the path and lets the browser infer the host (via the url being visited).
For example, if you were editing the HTML of a page here on Stack Overflow, the absolute link to this question would look something like this,
http://stackoverflow.com/questions/26379795/redirecting-to-aspx-in-a-different-domain
While the relative one would look like this,
/questions/26379795/redirecting-to-aspx-in-a-different-domain
In the case of the latter one, the browser would be left to assume based on context that you wanted to go to that path on http://stackoverflow.com/. There's a bit more to it, and variations on that syntax exist. But that's the gist of it.
So, getting back to your question, yes. You will probably have to update the ASPX pages. Relative links are best practice in most cases, which explains why they were used in your code, but you've got an exception. It's probably going to be easiest to just go through and change whatever links you need, to point to the main domain. But for what it's worth, that should be a relatively easy fix, once you get the files.
Alternatively, you could set up a rewrite rule or redirection policy on your landing page servers to automatically 301 redirect any requests that contain search information off to the main server, but that's definitely a workaround approach, and there will be a performance hit in doing so. The one and only advantage that I can imagine to doing that is that you wouldn't need to get the pages from the third party, but it sounds like that wouldn't be a bad idea to do anyway.

Find the actual page opened from the URL in the asp.net

HI so i keep running across websites which when looked through or searched (using their own search function) return's a static URL ie.) ?id=16 or default.aspx no mater what page of the website you visit after the search has been performed. This becomes a problem when i want to go directly to a post/page within one of these sites so i'm wondering. If anyone knows How could i actually find out what the absolute URL is.
So that i can navigate straight to it. I'm not really familiar with coding but have tried looking in the page source but i wasn't really able to gleam anything from there.

It all really depends on what you're trying to find, as far as finding a backway to locate a absolute path, is highly doubtful. If the owner of the site(most blogs) want you to have a perma link to a page, they use url-rewriting for putting things in the URI like title page and such. Alot of MVC sites do this now.
The '?id=16' you're seeing is just a query string, a holder for other logic they are doing.

Find every instance of a CSS id/class across a whole site

Before making a CSS change that might possibly have unintended consequences, what's a good way to find where else on the whole site (not just this page) that id or class is used? (It doesn't have to be exhaustive, and semi-manual processes are ok, too.)
For a bit of context, it's a Joomla-based site with a lot of content, and I'm not yet familiar with most of it. The id in question has a two letter name, and I have no idea where else it might be used. I don't have direct access to the server for any grep-like approaches.
The only technique I can think of is using Stylish to make an obvious change to that one selector, and browsing the site for a bit to see where it pops up.
The easiest way would be a local grep, but since you don't have access to the server, try downloading it locally using wget:
wget -r -l --domains=http://yourdomain.com http://yourdomain.com
That'll recursively retrieve pages from your domain to an infinite depth, but only following links to pages within your domain.
Once it's on disk, do a local grep and you're golden.
I use unused-css.com for this sort of thing. You simply put in your webpage, and it will look through the whole site (incl. login) and give you the CSS that you actually are using.
I've found it to be 95% correct - but it only doesn't pick up on things like some CSS browser hacks and some errors (ie. the CSS only displays after an error), so it should work fine for this.
You could also check the original template (assuming the template is a commercial one) to see where the id perhaps should be (they usually lay everything out in their demo template), but unused-css won't tell you exactly where it is used, only if it is or not. For that, I'd start with a view-source -> find on the major pages, and then try other mentioned solutions.
Get the whole site's source tree into an IDE like NetBeans or Eclipse and then do a recursive search for id="theid" on the root folder.
If this is not possible, how are you updating the CSS?
Assuming you don't want to do the grep approach:
Is the ID in question appearing in the actual content area of the page, or in the 'surrounding' areas? If it seems like it's not part of the content, but rather appears in a template, you could search the template files for it. As you're updating the CSS, I'm going to assume you can at least get a hold of the template files. Many text editors/IDE's will let you do a 'global search'. I'd load the template files in TextMate (my texteditor of choice) and do a "search in project" for the particular ID.
That will at least give you a semblance of an idea of where in the site that ID shows up. No, it won't be every 'page', but you'll know what kind of page it appears on (which, with a CMS, is really what you're after).
If the ID in question appears in the content, that is, it was hand-entered by content creators, you'll have to go another route. Do you have access to the database? If you can get a dump of the database (I think Joomla! is MySQL based), you can open the sql in something like Sequel Pro and do a search in the content records for that ID.
This is not actually as hard as it sounds. First place to look the index.php file for the template. This file should be pretty small without a ton of code unless the template is from a developer that uses a template framework. If the ID is in there, then it will show up on every page in the website since this is the foundation that every page is built on.
If you don't find it in there, then you need to determine whether it is displaying in a module position or in the component area. You should be able to tell the difference by looking at the index.php file from the template.
If it's in a module position, then the ID should only show up in instances of that particular module.
If it's in the component area, then it should only display in any pages being created by the component. That does leave the possibility of it affecting many elements you don't want changed. But there is a solution for that. you can use the page class suffix in a menu item to add a unique id/class to the page you want to change (depends on your template). With that unique suffix you can create a specific selector that will only affect the pages you want to change.

Issue with IHttpHandler and relative URLs

I've developed a IHttpHandler class and I've configured it as verb="*" path="*", so I'm handling all the request with it in an attempt of create my own REST implementation for a test web site that generates the html dynamically.
So, when a request for a .css file arrives, I've to do something like context.Response.WriteFile(Server.MapPath(url)) ... same for pictures and so on, I have to response everything myself.
My main issue, is when I put relative URLs in the anchors; for example, I have main page with a link like this Go to Page 1 , and in Page 1 I have another link Go to Page 2. Page 1 and 2 are supposed to be at the same level (http://host/page1 and http://host/page2, but when I click in Go to Page 2, I got this url in the handler: ~/page1/~/page2 ... what is a pain, because I have to do an url = url.SubString(url.LastIndexOf('~')) for clean it, although I feel that there is nothing wrong and this behavior is totally normal.
Right now, I can cope with it, but I think that in the future this is gonna bring me some headache. I've tried to set all the links with absolute URLs using the information of context.Request.Url, but it's also a pain :D, so I'd like to know if there is a nicer way to do these kind of things.
Don't hesitate in giving me pretty obvious responses because I'm pretty new in web development and probably I'm skipping something basic about URLs, Http and so on.
Thanks in advance and kind regards.
First of all I would take a look at the output HTML delivered to the browser and specifically the links that you are describing.
You say that the link is Go to Page 2 but according to your result I would guess it is more like Go to Page 2.
You can confirm this by placing a brakepoint in the handler and when it triggers with "~/page1/~/page2" look in the address bar of your browser and it should say something like "http://www.example.com/page1/~/page2"
You should first look at the code generating the link. If it is generated from some kind of function call, make sure you get the web address and not the script address.
In any case these kind of links that switch between first level pages should all start with a "/" indicating that their location is relative to the root of your website rather than relative to the current shown page.

how to get search engines to understand a DB driven asp.net site

All,
This would seem like a fairly basic asp.net question - but in all my years of coding, I've never really thought about it.
Say you have a asp.net 2.0 site with only a masterpage and a default.aspx and its a blog that saves all the data into the database. Links on the side are generated automatically. So ... the URL is always just http://www.XXXXX.com/default.aspx.
So, with that being the case, what do you need to do so that ... say google ... knows about all the different blog entries and links directly to the entries instead of just the base URL?
Is it as simple as changing the forms method to: method="get"?
Thanks, L. Lee Saunders
There are at least two solutions:
Search engines understand query strings, so just add the article IDs to the URLs in your anchor tags -- no need to even use a form control.
Use URL rewriting to expose one set of URLs to the outside world (like /article-title/1234/) in your anchor tags, and then modify the URL to be default.aspx when it arrives at your site; the page could then pull the article to be displayed from any number of places, including but not limited to a query string.
You could have a REST webservice so that you can just use urls to navigate the site, and perhaps have a front page with some new posts, so that the spider can navigate the site..
As an example, look at the urls for SO, it is easy for a spider to navigate this database-driven website.
Create a page that just serves up XML Sitemap (the data obviously being pulled from your database) and submit the sitemap to Google.
Google will then index any links in your sitemap.
(This assumes that these is some difference between each article - e.g. a Querystring key/value).
Useful Link(s):
Web Sitemap Generators
Google Sitemap Validator
Google Sitemaps for ASP.NET 2.0 (there are about a gazillion interesting links off the back of this as well).
some sort of URL rewriting may be an answer
I wouldn't recommend a postback for your situation, it can get ugly for refreshes etc. So, yes, change the method to "get"
Then, say your page of, default.aspx?postid=12345 will get translated into /mm/dd/yy/this-is-my-post.aspx

re-rendering a site within an iframe?

I want to make a site where there user can basically navigate the web from within an iframe. The catch is that I'd like to be able to have more control over what is rendered within the iframe. Specifically,
I'd like to be able to filter out images or text, disable forms etc.
I'd also like to be able to gather feedback such as what links the users clicked on.
Question 1:
Is this even possible using a standard back-end scripting language (like php), with html and javascript on the frontend?
Question 2:
Would I first need to grab the source of the site before it is rendered, then do whatever manipulation is necessary, and finally re-render it somehow?
Question 3:
Could somebody please explain the programming flow that would occur here (assuming its possible)?
I think you would probably want to grab the source of the of site (with server-side code) before rendering it. You might run into cross-site scripting issues if you try to use JavaScript. Your iframe would load a page like render.php and pass the address of the page to render os a querystring parameter. Then use regular expressions to find elements in the HTML that render.php downloads from the address. Rewrite the HTML as necessary and then write it all out to the iframe.
Rewrite links so that that the user is taken to a page you control and redirected onto a target site if you want to track where people are going. Example: a link in the page needs to go to google.com. You would send them to tracker.php?target=http://google.com. You control tracker.php and can log each load of this page and then redirect the user to the target site.
Update:
Another possible solution is to use Apache or other server to proxy the target website. There are modules like mod_proxy for this. There may also be modules that let you parse the HTML or you could roll your own.
I should point out that even the best solutions offered to your question will be somewhat brittle if you do not have full control over the target site. You will want to have lots of error handling or alerting.
You can have a look at this. It uses iFrame really well, and maybe even use the library it has.
