I have a web application that is using UrlRewriting. Now I want to set it that if the user enters the page with a url in re-written format, all the links apply the same format, otherwise they remain the same (with normal query strings).
Is there a way that I can get a list of query strings that are in the links without parsing the string?
Try the HttpUtility.ParseQueryString

I came across an unusual URL structure on a site. It looked like this:
https://www.agilealliance.org/glossary/xp/#q=~(infinite~false~filters~(postType~(~'post~'aa_book~'aa_event_session~'aa_experience_report)~tags~(~'xp))~searchTerm~'~sort~false~sortDirection~'asc~page~1)
It seems the category, pagination and sort options of a widget on the page injects and reads through these values. Does this format for storing data in the URL have a name, or is this an esoteric format someone made?
What's the purpose of doing this over using regular GET params, or at least using a more conventional format after the fragment?
If you inspect the URL carefully, you'll see that the parameters you describe are placed after the fragment (#), meaning they're not sent to the server but used by the client instead.
In this case, the client (JavaScript) builds them into something like an ElasticSearch query that's then POSTed to the server, in order to update listing you see on your screen.
I'm trying to migrate my ASPX site to Kentico, and as part of my task I'm migrating URLs. I need to preserve my URL structure, so I need to keep URLs which look like : "foo.com/bar.aspx?pageid=1".
I checked page's "URLs" property tried to use wildcards, some patterns like /bar/{pageid}- /bar/{?pageid?}-, etc but Kentico always replaces question marks.
Is there a way to achieve that via the admin interface?
You don't need to do anything in order to use "foo.com/bar.aspx?pageid=1" url.
Create a page under the root and call it bar, so you'll get a page # foo.com/bar.aspx. Kentico and/or .net does not care what you add to a url after question mark, so foo.com/bar.aspx?pageid=1 will work as well as foo.com/bar.aspx?someparam=sdf, or foo.com/bar.aspx?id=1&p=3&t=3.
You may (or may not) implement some functionality based on query string (e.g. paging), so it will parse query string and act in appropriate way.
By default Kentico UI does not handle adding URL aliases with URL parameters like you show. There is an article on the DevNet for a URL Redirection module which has code you can import into your site to allow you to perform these redirects within the Kentico UI. I'd suggest using this approach.
Unfortunately, I can't share a code sample since it's an article but it also has a link to download the code too. This appears to only be coded for Kentico 8.2 right now but I'm guessing you could do some work to make it work for other versions if you needed.
I think there are few concepts that you are clubbing here. I will start with your line code here
/bar/{pageid} - {pageid} is a positional parameter in Kentico's language if you choose to use dynamic URLS based on patterns. SO if you have a code that relies on pageid parameter to fetch some data then Kentico will pass that value. E.g in case of /bar/420, it will pass pageid as 420 different web parts on your template
/bar/{?pageid?} - This will search for query string parameter "pageid" on the request URL and replace its value here. So if you passed foo.com/bar.aspx?pageid=366, the resulting URL will be /bar/366
The #1 is positional parameter and #2 is the way in which Kentico resolves query string macros.
I hope this clarifies.
I have an MVC3 Action that takes a parameter (a URL) that may have a query string in it. My action signature looks like this:
GetUrl(string url)
I expect to be able to send it urls, and it works every time unless there is a query string in the url. For example, if I navigate to:
MyController/GetUrl/www.google.com
the url parameter comes accross as "www.google.com" -Perfect. However, if I send
MyController/GetUrl/www.google.com/?id=3
the url parameter comes accross as "www.google.com/" How do I get MVC3 to give me the whole URL in that parameter? -Including the query string?
It's simple enough to just URL.Encode the passed in URL on the page but you're opening your self to some possible security problems.
I would suggest you encrypt the url then encode it then pass that as your value, the protects you from having people just passing in anything into your app.
That's because system considers id=3 as its own query string. When you construct the link in the view, you need to use #Url.Encode to convert raw url string to encoded string to be accepted as parameter of the controller.
I'm trying to scrape an ASP.NET page with Excel. Unfortunately, the page only returns 50 records at a time, of several pages. Excel's native Web Query module only picks up the first page. I want all the pages.
Like most (all?) ASP pages, there are a few hidden variables sent back to the server when requesting a new page. The important ones are _VIEWSTATE and _EVENT_VALIDATION.
I've written a VBA function that gets the HTML source of the page and scrapes these variables from it.
I've also written an .iqy page, which allows for POST requests in it. It looks something like this:
WEB
1
http://www.myaspwebsite/search/search_List.aspx
__EVENTTARGET=&__EVENTARGUMENT=&__VIEWSTATE=%2FwEPDwULLTEy[....truncated ..50k characters..]Mhudyk5U6u8%2BBpvxDPN8R4%3D&__EVENTVALIDATION=%2FwEWFQL%2FkN%2FBCgL6g%2B5vAvfY06EOAoic4qIIAome%2Bf4PAuOrjYgIAuKrjYgIAuGrjYgIAuCrjYgIAuerjYgIAt7e34UPAvuL7m8CtuLToQ4CiaTioggCyKX5%2Fg8C4tv1sAgC49v1sAgC4Nv1sAgC4dv1sAgC5tv1sAgC%2Fd7fhQ%2BU8QRtxd7MM4Bpa%2F%2FZC7I64eUh3Q%3D%3D&ctl00_RadMenu1_ClientState=&ctl00%24ContentPlaceHolder1%24NavBar1%24PageNoDropDownList=2&ctl00%24ContentPlaceHolder1%24NavBar1%24btnGo=Go&ctl00%24ContentPlaceHolder1%24NavBar2%24PageNoDropDownList=1
Selection=AllTables
Formatting=None
PreFormattedTextToColumns=True
ConsecutiveDelimitersAsOne=True
SingleBlockTextImport=False
DisableDateRecognition=False
DisableRedirections=False
This iqy page successfully retuns the desired results if the post query is placed in the file.
I can also use this .iqy page programmatically in VBA and assign the POST query dynamically using QueryTables. However, I get told that my query returned nothing.
I suspect this is because of the length of my argument. The VIEWSTATE alone is about 50k characters. I've tried printing the argument string to a file and it truncates it. However, I can read the same string from a file and use it dynamically successfully.
My questions are : Am I going about this the best way? What limitations should I be aware of when doing this? Also, is there a limit to string size in Excel?
According to Microsoft's documentation on Visual Basic strings (same value applies to VBA strings):
A string can contain from 0 to approximately two billion (2 ^ 31) Unicode characters.
That is more than enough to handle a 50k string. A simple way to bypass IDE line limits and immediate window printing limits would be to print the string into an Excel cell and then read it back into a variable when you need to use that piece of data.
I want to extract some keywords out of a query string for a search application in asp.net.
I decoded the url string first, so it's plain text
I have this to start with, but I want to add a keyword group
([\?\&])q=[^\&]+[\&]?
I get this ?q=harbour landing dental&
I'd like to trim off the stuff for pure words, but not sure if that's possible
I also have a long list of possible query string value fields that I want to check against
?q=
#q=
?qs=
&qs=
Why don't you just use the HttpRequest.QueryString collection?
If you have access to the HttpRequest you should just use the HttpRequest.QueryString property.
If you don't have access to that and only have the actual query string as a string you should just use the HttpUtil.ParseQueryString function to get the NameValueCollection.
