Get URL from Query Parameter

SAMPLE DATA URL

_http://abc.com/cache.ashx?feedURL=http://search.twitter.com/search.rss?q=from%3AAbbottNews&rpp=3&clientsource=TWITTERINC_WIDGET&include_entities=true&result_type=recent&1334673762143=cachebust

I'm try to get value of query parameter FeedURL and below what I get;

Actual: http://search.twitter.com/search.rss?q=from%3AAbbottNews&rpp=3&clientsource=TWITTERINC_WIDGET&include_entities=true&result_type=recent&1334673762143=cachebust

What I'm getting: http://search.twitter.com/search.rss?q=from%3AAbbottNews

Required : I need the complete URL.

Note: It truncates from second parameter onwards

Dirty Solution:
I tried all suggestions, but I felt there is no better solution. There is no other go, I did a dirty solution to get the right part of the URL completely.

/// <summary>
/// Get Feed URL from raw URL
/// </summary>
/// <param name="rawURL"></param>
/// <returns></returns>
public static string GetFeedURL(string rawURL)
{
    int index = rawURL.IndexOf("=");
    string _rawURL = rawURL;

    if (index > 0)
        _rawURL = _rawURL.Substring(index).Remove(0, 1);

    return _rawURL;
}

The URL you provide, while valid, is not going to parse the way you expect; it'll be parsed the way it currently is. Nested query strings are not supported unless the ampersands are encoded.

You need to URLEncode your URL Variables when adding them to the URL...

url = "http://url.com?id=" + HttpUtility.UrlEncode("...");
Response.Redirect(url);

.. and URLDecode them to work with them after the request...

HttpUtility.UrlDecode(Request.QueryString["id"]);

Otherwise the QueryString request doesn't know how to handle all the extra ?'s and &'s.

It looks like this may be due to the fact that the first "&" character in your FeedUrl may be getting treated as a query parameter for the outside query string. You may need to encode the FeedUrl first. This is just my initial gut feeling.
