[squid-users] Vary object loop returns

[joe]

right the acsess.log dose not show  those  %20 
20 ar space in real accept-encoding: gzip, deflate   <-- notice the space
wen it reach function
varyEvaluateMatch  it shange some how to 20   and the %  is mark  the one
internally wen its used by the destination server  it has no mark %20   
example  accept-encoding="gzip,%20deflate"  <--here the server use gzip
notice its not marked
accept-encoding="%20gzip,%20deflate,identity" <-- here identity used by the
destination sever sending this to squid with mark %20   depend i gess on
dest..server compression can handle
so those wen it come to squid they use the vary as extra key to save the
object in cache 
we dont need them   since there is many browser or app  asking the
dest...server for different compression
hit %  become low cause squid use vary with wat ever string as key to save
the object
now for us  its very bad caching and if we remove filtering out those with
%20 so other variant browser can benefit of those object from the cache  so
the 20 is hex converted from the string space to 20  and the %  is mark as i
understand it after lots a research
