           Summary: HttpRequest.QueryString is parsed incorrectly
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.4.x
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Sys.Web

The following URL causes is parsed incorrectly by HttpRequest.QueryString:

http://dev/Session/New?ReturnPath=%2FFile%2Fabc%2F%3Fdef&ReturnQuery=block%3D23%26z%3Dg

After decoding the URL becomes:

http://dev/Session/New?ReturnPath=/File/abc/?def&ReturnQuery=block=23&z=g

The entries in the NameValueCollection are as follows:
0) ReturnPath = /File/abc/?def
1) ReturnQuery = block=23
2) z = g

instead of the expected

0) ReturnPath = /File/abc/?def
1) ReturnQuery = block=23&z=g

This works as expected on the .NET FX, and if I do the following:

NameValueCollection qs =
HttpUtility.ParseQueryString(Request.RawUrl.Substring(Request.RawUrl.IndexOf('?')));

On cursory inspection of the code it looks like the code is using Url.Query to
parse instead of worker_request.QueryString (which is parsed from the raw URL).
