Description Sönke Schwardt-Krummrich

2015-11-24 21:59:36 CET

This bug covers the UCS part of that bug and adds squid/redirect/children via UCS 4.0 erratum of univention-squid.

+++ This bug was initially created as a clone of Bug #34045 +++

By default, squid.conf starts 5 authentication helpers and 5 URL redirector processes. That might not be enough for a school:

---cache.log
 WARNING: All ntlmauthenticator processes are busy.
 WARNING: 10 pending requests queued
 Consider increasing the number of ntlmauthenticator processes in your co
nfig file.
...
 WARNING: All redirector processes are busy.
 WARNING: 5 pending requests queued
 Consider increasing the number of redirector processes in your config file
---


 ucr set squid/ntlmauth/children=50
 ucr set  squid/basicauth/children=50

Since there is not an UCR variable like squid/redirect/children, the change has to be made in the local configuration file:

#---/etc/squid3/local.conf
#...
url_rewrite_children 20
#---

There is an old bug about this: Bug #18456

squid/rewrite/children is unset by default and defaults to squids default value (5).
