Subject Re: [users@httpd] How to disable web accelerators

I think most sites which block it do it by checking the User-Agent header. 
See http://httpd.apache.org/docs/2.2/howto/access.html and also the docs for 
mod_access if thats what you really want.

However if the web program changes its User-Agent to match that of a well 
known browser like IE or FF then nothing can be done. Sometimes cookies 
provide a certain higher degree of challenge to web accelerators especially 
download managers. But as far as I know theres nothing really to stop 
FasterFox since it has access to the same user agent and cookies. Have you 
come across a site which warns you against fasterfox??? you could check the 
user agent that google web accelerator uses and block it.

Finally the only alternative if your really being pummeled by multiple 
simultaneous partial requests for the same file, is to disable partial file 
transfer, though i'm not sure how you do this in apache. There are tradeoffs 
if you do this - people who visit your site might get frustrated and you may 
not even end up saving bandwidth.

If your actual aim is to reduce bandwidth usage I suggest you take a look at 
mod_throttle and probably packetshapers.
