So, using JavaScript I have a parser for a URL:

   function parseUrl(url) {
      var e = /((http|https|ftp):\/\/)?((.*?)\/)?((.*)\/)?(.*)?/;
      if (url.match(e)) {

         return  { url:     RegExp['$&']
            , protocol: RegExp.$2
            , host:     RegExp.$4
            , path:     RegExp.$6
            , file:     RegExp.$7
            , hash:     RegExp.$8 };
      }
      else {
         return  {url:"", protocol:"",host:"",path:"",file:"",hash:""};
      }
   }

 
As you can see, the RegExp is:  /((http|https|ftp):\/\/)?((.*?)\/)?((.*)\/)?(.*)?/

Given a URL like: http://regexadvice.com/forums/AddPost.aspx?ForumID=68
The variables would result:
url:    http://regexadvice.com/forums/AddPost.aspx?ForumID=68
protocol: http
host:    regexadvice.com
path:    forums
file:     AddPost.aspx?ForumID=68
hash:    

 -or-

Given a URL like: AddPost.aspx?ForumID=68
The variables would result:
url:    AddPost.aspx?ForumID=68
protocol:
host:   
path:   
file:     AddPost.aspx?ForumID=68
hash:   

 

I haven't set up the hash portion, and I'm not worried about that yet.  So the above works exactly how I want it to.  The issue though is when something like below happens:

Given a URL like: AddPost.aspx?ForumID=http://www.something.com/fldr/whatever.html
The variables would result:
url:    AddPost.aspx?ForumID=http://www.something.com/fldr/whatever.html
protocol:
host:    AddPost.aspx?ForumID=http:
path:    /www.something.com/fldr
file:     whatever.html
hash:  

 How I would like it to work is like the above.  In this case, the desired result would be:

Given a URL like: AddPost.aspx?ForumID=http://www.something.com/fldr/whatever.html
The variables would result:
url:    AddPost.aspx?ForumID=http://www.something.com/fldr/whatever.html
protocol:
host:   
path:   
file:     AddPost.aspx?ForumID=http://www.something.com/fldr/whatever.html
hash:  

Hope that makes sense.  I appreciate the help,
