Using FastCGI Cache with Affiliate tracking software (lots of query strings)

[nick1]

I just realized that my FastCGI caching may be rendered useless…

We are using affiliate tracking on our site (powered by EasyEngine). So 99% of our hits to the site include query strings in the URL.

/?affilate_id=123456

I know that the server config says to bypass cache if there’s a query string in the URL.

So does this mean that FastCGI cache is rendered useless? I think we still need some sort of caching mechanism to handle traffic spikes and heavy traffic days. Is this possible with W3TC or WP Super Cache?

You can cache the site including quueries,
There will be cache for each query.

add following in your sites nginx conf.

  
if ( $arg_affilate_id != "" ) {   
     	 set $skip_cache 0;  
}
