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.

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


I am not sure if this is the right place to ask or not. How do I go
about disabling the use of web accelerators like FasterFox or the Google
Web Accelerator? I have noticed that several sites now have a warning pop
up if you are using such a device and refuse you access until it is
turned off.
