[squid-users] proxy auth timeout config

[Rolf <rolf@xxxxxxxxxxxxxx>]

hello

Can someone clarify for me the squid config directives that control how 
long proxy auth credentials are kept for?

I have basic auth working fine here and I think I set it up for re-auth 
every hour. But I have been noticing that sometimes one can go for days 
and in any event much longer than an hour before being asked for 
credentials again. The username is logged for proxy activity ok, its 
just not asking for auth as regularly as I expected.  The only perfect 
way to get re-auth'd is to quit to restart the browser.

What directives do I need to set to get this working so that say, every 
hour, auth is requested (irrespective of user activity)?

thanks

rolf.
