My server gave me the error 406, because they had a mod_security on the Apache server. It was because I tried sending this string

Code:
http://www.oddim.com/functions.php?CALL=NEWS_FEED&TYPE=1&STATUS=rawrtest%rawrtest
which I of course encoded to (using encodeURIcomponent)

Code:
http://www.oddim.com/functions.php?CALL=NEWS_FEED&TYPE=1&STATUS=rawrtest%25rawrtest
I got the mod_security disabled but I wanted to know If I'm programming in a non-secure way that it triggered that mod.
