Sorry to bring this problem back. I have squid cache server running on freebsd-5.0-SMP WCCP and transparent support with version squid-2.5stable5 and squid-2.5stable7 .. and of-course --enable-underscores installed.
Lately our customers having problem accessing "_" hostname as in 'blogspot.com' domain. The browsers (IE and Firefox) error is: ==== While trying to retrieve the URL: http://www.pingu_art.blogspot.com/ The following error was encountered: Unable to determine IP address from host name for www.pingu_art.blogspot.com The dnsserver returned: DNS Domain 'www.pingu_art.blogspot.com' is invalid: Non recoverable errors. ==== Tailing the access.log resulting: 1103338562.018 14 202.53.253.20 TCP_MISS/503 1609 GET http://www.pingu_art.blogspot.com/ - NONE/- text/html I tried to use Lynx on my cache server and having problems resolving that domain and unable to load any data from it. BUT, when I tried to dig and nslookup command, it resolved beautifully: ;; ANSWER SECTION: www.pingu_art.blogspot.com. 3d23h40m58s IN CNAME blogspot.blogger.com. blogspot.blogger.com. 40m59s IN A 66.102.15.101 ;; AUTHORITY SECTION: blogger.com. 1h52m9s IN NS ns1.google.com. blogger.com. 1h52m9s IN NS ns2.google.com. blogger.com. 1h52m9s IN NS ns3.google.com. blogger.com. 1h52m9s IN NS ns4.google.com. **The DNS server is in other server using BIND 9.X.X And I have I cache server (Cache Flow VA Linux cache engine) that resolve this domain properly and load the particular sites with no error with the same DNS settings. Notes: - I haven't try to clear the cache files that have been running for approx. 7 months. - I tried 'always direct on domain_regex _ that suggested on previous email, still didn't work Question: - DNS resolving problem on HTTP WCCP redirect packets ? or Squid WCCP problems ? or anything else ? - Any hints on this problems ? Thank you. irfan_dp (sorry with my poor english)
