Regular Expression to parse string url links

Question

I am looking for a way to parse url link into following segments without using System.Uri

/Default.aspx/123/test?var1=val1

I need to break down this url link into values:

File
PathInfo
Querystring

string pattern = @"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)"

it is a bad practice just posting links. If the link broke your answer says nothing – sra May 26 '11 at 05:39

fair enough. but you'd get the same answer by googling "regular expression url", to take credit for their work seems ...wrong. – bryanbcook May 27 '11 at 04:21

Here is my code:

   var match = Regex.Match(internalUrl,
                            @"^\/([\w|\/|\-|\,|\s]+)\.([a-zA-Z]{2,5})([\w|\/|\-|\,|\s]*)\??(.*)",
                            RegexOptions.IgnoreCase | RegexOptions.Singleline |
                            RegexOptions.CultureInvariant | RegexOptions.Compiled);
    if (match.Success)
    {
        var filePath = match.Groups[1].Value;
        var fileExtention = match.Groups[2].Value;
        var pathInfo = match.Groups[3].Value;
        var queryString = match.Groups[4].Value;

        log.Debug("FilePath: " + filePath);
        log.Debug("FileExtention: " + fileExtention);
        log.Debug("PathInfo: " + pathInfo);
        log.Debug("QueryString: " + queryString);
    }
