Hi, Im having some confusing trouble with an external acl based reply_body_max_size setup, but only when the ext_log is brought into things. I have an external acl setup as such: > external_acl_type response_size_type ttl=300 children-startup=2 children-idle=1 children-max=10 %URI %EXT_LOG %TAG python max_file_size_ext_acl.py which is used to check against some external data to cache the response for the reply_body_max_size directive to use, an example of which is this: > acl response_size_31 external response_size_type 31 10.0.1.26 > http_access allow response_size_31 > reply_body_max_size 31 MB response_size_31 now this works perfectly fine, no issues what so ever, until the external acl alters the EXT_LOG (and passes it back), pretty much any alteration to the ext_log data causes squid to basically ignore the answer it gets back from the external acl and continue on. The external acl can take in the ext_log and pass it untouched out the other side no issues too, so it doesnt appear to be simply the fact its passing the ext_log back. Im really stumped at to whats going on here, any help would be appreciated. Cameron Charles
