I have an index.html file which I am reading via cffile.

I want to search all of the href string and append with a custom string. For example, the file will read a bunch and a href links ( <a href="http://www.google.com">Google</a>,<a href="http://www.yahoo.com">Yahoo</a> etc). I want to be able to append all of the href with something like this (<a href="http://www.mysite.com?redirect=http://www.google.com">Google</a>. I would really appreciate your help in advanced. Thank you.

    Something like this should work at a basic level, assuming the HTML is valid:

    <cfset newHTML = ReReplaceNoCase(html, "(href=[""'])([^""']+)([""'])", "\1http://mysite.com/?redir=\2\3", "ALL")>

    It's using backreferences in the regex the parenthesis to group the parts of the match, which are then referred to as \1 \2 and \3 in the replacement string.
