Missing ? in urls with query string and url rewriting

using mod_rewrite, the a URL with a query string looks a bit odd because it doesn't have a ? to denote the query string itself.

For example:

http://www.abc.com/app/login&id=1231231231&option1=abc

It really should be:

http://www.abc.com/app/login?id=1231231231&option1=abc

To solve that, when need to

• change url rewrting rules (probably)
• make some changes in the request_uri() function
• make some changes in the url_for() function (easy)
