Re: [squid-users] Re: have you ever seen this?

But these are dial-up users that get this account by buying prepaid
internet card, i do not know them. I changed my squid.conf and increased
'request_header_max_size' to 30 KB . that problem has been solved. but i
am not sure that this optin can affetcs the performance of squid or not (i
mean decrease the performance).BUT i saw another warning in my cache.log
after this changes.what are they?

WARNING: failed to unpack meta data
WARNING: failed to unpack meta data
WARNING: failed to unpack meta data

IS there any relation between 'request_header_max_size' and above errors?
