WebRequest & relative paths

[SpaceMarine]

did something change in the WebRequest object from .NET 1.1 to 2.0?

i swear i used to be able to pass relative URLs into the WebRequest
method, like so:

string relativePath = "/foo/bar.html";

WebRequest request = HttpWebRequest.Create(relativePath);
WebResponse response = request.GetResponse();

....now that generates an exception:

"Invalid URI: The format of the URI could not be determined."


so then i figured out how to create a full URL path ("http://...")
like so:

string relativePath = "/foo/bar.html";

//get the main url
string authority =
System.Web.HttpContext.Current.Request.Url.GetLeftPart
(UriPartial.Authority);

//add the supplied relative path
Uri uri = new Uri(authority + relativePath);

WebRequest request = HttpWebRequest.Create(uri.AbsoluteUri);
WebResponse response = request.GetResponse();


....that works, but im still wondering -- did this change?



thanks!

Thanks SpaceMarine, very useful and the shortest solution I found for this issue, with no string manipulation.

Depending on directory structure maybe we need to insert Request.ApplicationPath:

Uri uri = new Uri(authority + Request.ApplicationPath + relativePath);


Didn't test it on 1.0, but is a little bit cumbersome to make it working; I suppose it should be something similar to ResponseRedirect(~/page.aspx)...? you right...
