Question Response.Redirect "?src=" variable

[vbnewbi]

Hi, I'm fairly new to VB.net. I'm creating a basic website in Visual Web Developer 2010 Express in ASP.NET/VB and I'm trying to find out how to use Reponse.Redirect with a "?src=" parameter to redirect to another site and keep the same source string in the redirected site.

For example:

Visitor goes to http://www.test.com?src=source1 and gets redirected to http://www.site-a.com?src=source1
Visitor goes to http://www.test.com?src=source2 and gets redirected to http://www.site-a.com?src=source2

and so on

I don't want to hard code:

Response.Redirect("http://site-a.com?src=source1")

for each possible source. I want whatever source string is in the original visit to pass into the Response.Redirect and show on the destination page, something like:

Response.Redirect(http://site-a.com?src=" + mysource)

But how do actually I code this in VB.net to read the source string in the first URL and automatically add it to the destination URL?

Thanks for any help on this.

whole query part as string Page.ClientQueryString Property (System.Web.UI)
or if you want to work with each key/value pair HttpRequest.QueryString Property (System.Web)

I do something like this, where the ReturnUrl = "myspace.com/gohere.aspx" and the original URL is : "myspace.com/washere.aspx"&ReturnUrl="myspace.com/gohere.aspx"

Dim strReturnUrl As String = Request.QueryString("ReturnUrl")

Response.Redirect(strReturnUrl)


Note that there should not be quotes around the URLs. I had to do that so this text editor did not try and make them into links
