In my blog at http://www.willswebworks.com/blog/2008/08/convert-email-addresses-in-source-html-to-images-without-modifying-the-source/, I explain how I devised a method to output plain-text email addresses in HTML source as images of those email addresses when Apache web server outputs the HTML to the clients browser. It takes advantage of a new feature very recently released in Apache 2.2.7. A regular expression substitution is performed on HTML to find email addresses and replace that code with an tag that refers to a tiny PHP script that generates the image. My example uses an image, but you can replace the email address with any spam email harvester obfuscation method you'd like by putting the appropriate code as the replacement value of the regular expression. The big deal? This method requires NO modification of the existing HTML code whatsoever. HUGE time saver, and this method can be propagated throughout an unlimited number of virtual servers running under the Apache server. I hope you see the possibilities as much as I do!
