I guess, your using wrong approach. You trying to find ready-to-use solution for /custom/ configuration. At maximum, you can find some bricks for this. And anyway you should build your custom solution yourself. Bricks is here: https://wiki.squid-cache.org :-) 14.03.2018 20:28, Danilo V пишет: >

AFAIK, SSL bump subsystem uses OpenSSL memory routines. So, first of all, most probably leaks (if any) can be OpenSSL-related, but not squid itself. Now let's see your config snippets. 13.03.2018 23:00, Aaron Turner пишет: > "Usually misconfiguration leads to memory overhead." > > This may be tr

"Usually misconfiguration leads to memory overhead." This may be true, but if you look in the list archives a few months ago I basically chased my tail in circles and nobody could tell me what I was doing wrong and so many of the docs are so old that they're worse then useless, they seem to sugges

"SSL bump" is the name of a complex Squid feature. With ssl_bump ACLs one can decide which domains can be 'spliced' (go through the proxy untouched) or can be 'bumped' (decrypted). Interception is not a requirement for SSL bump. Marcus On 13/03/18 11:44, Danilo V wrote: I mean SSL bump in exp
