I asked a question to get url as action input here. Now I have a new problem. The passed url to action changes from http://google.com to http:/google.com.

I want to know why and how can I resolve the problem.

P.S: I added this code to resolve but I think there may be another problems in future! the code is:

if ((url.Contains(":/")) && !(url.Contains("://")))
{
    url = url.Replace(":/", "://");
}

on an unrelated note, it looks like your code is replacing all depressed/undecided faces with slanty scared-looking faces. – Phillip Schmidt Aug 7 '12 at 19:54

The browser (or server) is replacing a double slash (illegal) with a single one.
Try it,

http://stackoverflow.com/questions/11853025//input-url-like-http-site-com-changes-to-http-site-com-in-action-input

(in Chrome) goes to:

http://stackoverflow.com/questions/11853025/input-url-like-http-site-com-changes-to-http-site-com-in-action-input

If I were you, I would remove the http:// from your path and add it later.

http://localhost:1619/Utility/PR/google.com/

Then, url = "http://" + url;

If you might get secure urls, add that to the route /http/google.com or /https/google.com

use regex:

string src = @"http://google.com";
string result = Regex.Replace(src, @"(?<=https?:/)/", "");

if you need to revert:

string src = @"http:/google.com";
string result = Regex.Replace(src, @"(?<=https?:)/(?=[^/])", @"//");

is it better than the code I wrote? – ahmadali shafiee Aug 7 '12 at 19:59
and do you know why it happens? – ahmadali shafiee Aug 7 '12 at 20:00
yes, my code replace href slashes in any string correctly, your code wrong if string would be like http://google.com http:/google.com – burning_LEGION Aug 7 '12 at 20:02
