TND's questions

On a website I am building, I plan to log the IP addresses of submissions, just in case it's necessary. I don't mind proxies, but outright spoofing your IP address would defeat the purpose.

To perform a complete GET action, (regardless of whether you receive or whether it went through or not) is a legitimate IP address required? Or a website be spammed with posts from random spoofed IP addresses?

(Is POST any different?)

I have this code somewhere in my .htaccess file:

RewriteRule /user/([a-zA-Z0-9]+) /iduser.php?username=$1

It should make /user/oliolio request iduser.php?username=oliolio, however it doesn't work. :(

Do you know why?
