Get the full QueryString from URL in ASP.NET

Question

I have an URL with the following format:

http://www.mysite.com/login.aspx?ref=~/Module/MyPage.aspx?par=1&par2=hello&par3=7

I use the content of the QueryString it to Redirect the user back to the page he was before logging in. In order to keep also the status of the page I need the parameters in the QueryString. The number of parameters changes depending on the Page calling the Login and its status.

Let's say I want to store everything in the URL after ref in the redirectURL variable. I tried:

 redirectURL = Request.QueryString("ref") // "~/Module/MyPage.aspx?par=1"

it gets everything after ref but ignores everything after the &(included). If I use:

 redirectURL =Request.Url.Query // "ref=~/Module/MyPage.aspx?par=1&par2=hello&par3=7"

it gets everything, ref included. In order to achieve my goal I need just to remove the first 4 characters from the redirectURL. But I think this solution is a bit "forced" and I am sure there should be some ASP.NET function that accomplish this task.

The &s in your URL are creating additional querystring arguments.

You need to escape the value of the ref parameter before putting it in the querystring.
This will replace the &s with %26.
To do this, call Uri.EscapeDataString().

When you fetch the property from Request.QueryString, it will automatically decode it.

Consider Encoding "~/Module/MyPage.aspx?par=1&par2=hello&par3=7" before passing it to the url.

Eg.:

String MyURL = "http://www.mysite.com/login.aspx?ref=" + 
                Server.UrlEncode("~/Module/MyPage.aspx?par=1&par2=hello&par3=7");

And then, you can get the redirectURL using:

String redirectURL = Request.QueryString("ref");
