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. Some of them are very,

The DNS entries TTL period has expired. 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.
