</div>

is it possible to use a value found within POST DATA as part of the  
cache key?

for example, the value of variable called ‘username’ to be part of the  
cache key.

so i basically want the cache to key to simply hash against the  
connecting IP and the ‘username’ POST variable.

proxy\_cache\_key “$remote\_addr$POST[username]”

thanks in advance
