Possible Fixes: The usage of htmlspeacialchars(), mysql_escape_string(), mysql_real_escape_string()
and other functions for input validation before passing user input
to the mysql database, or before echoing data on the screen, would solve these

Hey,
well actually you dont need a proxy server for http response splitting vulnerabilities,
you can carry out cross user defacement or cross user cache poisoning without one, http://www.digitalparadox.org/papers.ah
Using a proxy server will allow you to target many users by poisoning a proxy cache and thus causing a page forging or defacement. |

well thx, for remaining me 
i forget , if u want this effect will be taken by a big size number of users , so you have to poisoning a proxy server
but u can also poisoning only a user
