I have a website which content is created dynamically on the client using ajax, and I want to create a HTML snapshot for google crawler.
Since I Use ASP.net, my idea is to create an instance of WebBrowser control on the server, whenever google passes '_escaped_fragment_' parameter, then load my dynamic page on the server, and then return google the created page.
I have two questions:
1. Is there a better way to do this?
2. If there is no better way to do this, how should I implement it? should I use http handlers?
This may be late. Have you tried NHTMLUNIT(which is a wrapper to HTMLUNIT)?

I m developing a Single Page Application (SPA). So, I use to refresh the page's HTML's content dynamically using Ajax requests.
I'd like to register to the DoubleClick for Publishers program, but I m wondering if my SPA is able to integrate advertising due to its dynamic content loaded without refreshing the page.
I saw this link: https://support.google.com/dfp_sb/answer/3058726
So I assume it's ok. But I'd like to be certain before starting using DFP. Could someone confirm please?
Then, sometimes I m using external html pages that I still load using Ajax. Should I consider writing the advertising banners JavaScript inside these external views, or directly inside the master page of my app?
Last question: How can I manage users having an adblocker software installed? Am I allowed to detect the presence of an adblocker software using JavaScript and then execute some specific code for this kind of users?
I'm working in a SPA and working with DFP successfully. Here is my feedback to your questions:
So I assume it's ok. But I'd like to be certain before starting using
DFP. Could someone confirm please?
Yes, you can refresh the banners using the method you are refering in the link you shared
Then, sometimes I m using external html pages that I still load using
Ajax. Should I consider writing the advertising banners JavaScript
inside these external views, or directly inside the master page of my
app?
To load them externally will bring you to lower performance results. You can control everything from the main page and you will have better results.
Last question: How can I manage users having an adblocker software
installed? Am I allowed to detect the presence of an adblocker
software using JavaScript and then execute some specific code for this
kind of users?
This is something I have not started to work on it but you can detect (like forbes.com is doing on it website) and there are also projects on dealing with this.
I have an ASP.NET application with pages that use reportviewer. Can someone give me a hint on how to approach the following requirement:
I want to get the report as PDF file from the page, without user interaction. I know I can render the report to a filestream, but since there's no user opening it in a browser, I need to collect the filestream from another application that might run during the night.
There might be other approaches, like a webservice for example that could return the filestream to me, but this would also mean, I have to modify the setup of the datasources that the report receives it's data from. There are a lot of controls on the page, for supplying filter parameters. By using the page life cycle I can use what's already there.
I thought about wget, but haven't tried it yet, and I'm not sure how complicated logging in will be with cookies. I do have full control over the asp.net application though, so if I can modify something there to make it easier, I'd do it.
You can use the "WebClient" in .net application to get the response from the site.
Please refer the below link:

I am building a website, within a large intranet, that wraps and adds functionality to another site within the same intranet. I do not have access to the other site's source and they do not provide any api's for the functionality they provide. I need to, somehow, have my server-side code go to that site, fill in some forms, then press a submit button.
Is this possible? If so, how can I accomplish this?
Note: I am working in asp.NET if that matters at all.
Not the most efficient, but maybe WatiN can get you started:

Just look at the URL the form is supposed to submit to and the method it employs (POST or GET) and then send a request to that URL using the same method and put the field you want as parameters
Your server-side code is basically a web client to the other web site. You will need to write the code to send the HTML form data to the other web site and process the response. I would start with the System.Net.WebClient class. Take a look at System.Net.WebClient.UploadValues. That class/method will enable you to POST the form data to the web site via a NameValueCollection.
I'm working on a site at the moment that loads all of its browser popups by using page methods. This approach works but it's starting to get messy. I also view page methods as ways to perform small tasks, username availability comes to mind.
What other options are there besides page methods and the update panel?
You should look at the JQuery ajax functionality. http://api.jquery.com/category/ajax/
You can point the url of the AJAX request to an aspx page or an html page or pretty much any web resource that you like, as long as the request is handled on the server by some kind of HttpHandler. And as long as your callback handler is able to handle and display the returned resource
PageMethods sounding fine to me (which are essentially Webservices).
You could pull more data per request and use cache more. You could build a better JavaScript wrapper which satisfies the need for more tidiness.
You could choose another library: How to call a web service from jQuery
I am building a Flex Application that calls a .aspx page on the same webserver which builds a PDF report using SQL Reporting Services. When the report is built it prompts the user to open or save the PDF.
We are trying to find a way to display a Progress Bar to let the user know that the report they requested is being built, and then destroy the Progress Bar once the report is finished being built.
I've tried opening a new window using JavaScript and trying to catch when the window closes, as well as trying XMLHTTPRequest, but nothing to seems to work.
Does anyone have any suggestions?
There are 2 options:
Use the FileReference class in Flex to programmatically invoke your aspx file. You will be able to track the progress of the call from within Flex by listening to its events. But the users can only save the PDF, not open it.
Have an intermediate HTML page that displays a loading icon and then refresh itself to your PDF generating ASPX page. Encode your aspx url along with parameters etc and set it as a parameter to this intermediate page so it knows what to load.
If you don't have control over the page to be able to put JavaScript on it to hit a URL (or call back to the parent/opener), then you might consider whipping up an aspx page of your own to host a ReportViewer control, and display the report inside of that. This would require you to create a .NET website with a page and a web.config - you wouldn't need to do more than make it receive any parameters your report needs, and it would be do-able via inline-to-the-aspx code as opposed to requiring in-depth .NET knowledge.
Or, you could hit the SS-RS API and render the report directly. Here, you'd craft a URL with parameters for the report on the SS-RS API site to accept. I think, though I don't know for sure, that the SS-RS UI uses the API itself behind the scenes. By default the API is hosted in a site called "reportserver" - you might sniff HTTP traffic while the report is being rendered to get you started with the URL that you'd need to hit.
Another option not mentioned here is to create a .Net webservice, add it to your flex project and when it hits the result handler you know the file is created at that point.
