Hi Amos, Thanks for your quick answer. In our squid.conf we have configured: hosts_file /etc/hosts In that file we have: 213.229.135.77 rbcdexia-is.es Is this an easy way to resolve the domain? Thanks, Jaime. >>> El día 07/03/2012 a las 13:20, en el mensaje <4F575280.6030309@xxxxxxxxxxxxx>, Amos Jeffries <squid3@xxxxxxxxxxxxx> escribió: On 8/03/2012 1:00 a.m., Jaime Gomez wrote: > Hi all, > > First of all I want to apologyse if this question has been solved before but I haven't found anything related with this. > > We have a very weird issue with some https web pages.

Squid is looking up new ones when the timeout happens. Can your resolve that domain easily yourself? If not, that is the problem. If you can resolve it easily please add debug section 78,5 and make a new trace. Amos
