I'm using the following code to set the proxy on an HTTPWebRequest:
Dim proxy As New WebProxy("HOST:PORT")
...Then...
' Goto the final URL
request = CType(WebRequest.Create("[URL]"), HttpWebRequest)
request.Proxy = curProxy
[Code] .....
Now I put in a valid Proxy, don't run into any problems applying it, but IPChicken will always return my IP address, not that of the proxy.
What is the difference between those 2 classes in System.Net?How can I login to website using one of these classes, and how can I post to a forum?

View 1 RepliesI'm looking for a way to fill in various website details using a HttpWebRequest/WebClient. I can manage it quite easily using an invisible WebBrowser control, by manipulating the HtmlDocument, but for some reason I just can't quite grasp the way I would do it with a HttpWebRequest/WebClient. I've heard both of these can potentially submit info using the UploadData functionality etc, but I'm missing specificsI've done a lot of searching on google just for a basic example to get me started, but the only one that LOOKED informative was written entirely in German.Take, for example, this website. Let's just say I wanted to automate filling in my username and password into their respective boxes and then pressing the "submit" button. How would I start going about this, and how do I get the resulting page? (I'm assuming cookies that the page creates will keep your next webrequest going)

Is it possible to change/set my Internet Explorer proxy setting in VB.NET application? For example, change the proxy server IP.

request.Method = "POST"

I need to create an ASP.NET application to access a URL, when this application is live it is able to access the feed URL correctly as the clientaccesspolicy.xml and crossdomain.xml are on the server but only allow non-localhost connections so the debug version won't connect. How do I create a file, so this kind of link:
[URL]
Can be used to pass-through to the RSS feed service live URL like:
[URL]
So that I can develop my application via localhost as I can add a clientaccesspolicy and crossdomain file to this application so my Silverlight Application can access the live RSS service, while being developed without having to deploy it online every time I need to see what the application will look like.
A dummy RSS file is not suitable as I need to see various "Items" from the Feed.
