Query on PURGE behaviour...

[Michael Loftis <mloftis@xxxxxxxxx>]

I've got an inverse proxy setup running with Squid, and I was wondering 
what the specific behaviour of PURGE is.  In this case we've got a Varying 
header based on the browser and accept-encoding due to gzip-ed content, so 
my question is does a PURGE for a single URL purge *all* of the variously 
cached copies for the various browser+encoding strings?  I know it keeps 
separate cache entries for each.

I ask because someone might have an answer that'll save me some time 
experimenting or digging in code!

TIA!
