[squid-users] Connection problem when you reload in squid3.4

Wed Oct 26 17:36:16 UTC 2016

I have a problem with squid3.4:
The situation is:
I have a web application that writes into several files for example:
ip_lan.txt -> IP subnet of PC LAN
     mac_lan.txt -> Mac PC LAN subnet

These files are used by squid3 to allow access, so that whenever the 
application modifies these files have to do a reload to squid3 to 
recognize the new modifications.

also I use cahe_peer, internet service provider.

I can navigate normally, but when I reload, there as a connection 
outage, because what I receive from cache_peer is the following message:
--- ERROR IN THE BROWSER ------------------------------------------- 
--------------
ERROR
The requested URL could not get
the following error when trying to retrieve the URL is found: / Sports
Invalid URL
Some aspect of the requested URL is incorrect.
Some possible problems are:
Missing or incorrect access protocol (should be "http: //" or similar)
Missing hostname
There is an illegal double-escape on the path of the URL
There are illegal characters in the hostname; the underscore character 
(_) is not allowed.
Your cache administrator is admin at algo.com.
-------------------------------------------------- 
-------------------------------------------------- ----------
Then I do a F5, update the page and then functions, ie can browse normally.
Previously worked in the vercion 3.1 squid3 and not pass this, I could 
even make multiple reload, and this situation did not happen.

This configuration is practically the default brings the squid3.4.8, to 
Nonstop an ACL, the cache_peer and dns_nameservers.
I've tried reinstalling the server, only install squid and no other 
pakete, besides setting is minimal.
