mod_scrmable is an apache2 module to scramble a word only leaving the first and last letter in place. It works as a filter that hooks up to HTML output. The module filters html-tags and and scrambles all other words.
You may ask why did you build this, well after reading the above newspost on slashdot we just had to make an apache module to scramble HTML output according to the above algorithm. So the main reason is; because we can.
