If it's just your machine that's failing, then maybe something is misconfigured in your browser, or your browser is the only one pointing to a misconfigured proxy. The squid warnings are a tell-tale. Are you running the browser on the same box as the proxy? That often causes problems due to squid's default ACLs. share|improve this answer answered Mar 27 '10 at 12:30 Marcelo Cantos 7062715 @Marcelo can't get ur point...

If it fails, then it does not contact the second one. wget does. The first DNS listed is actually localhost, dedicated to the LAN. I should configure it to forward the requests http://www.squid-cache.org/mail-archive/squid-users/200903/0102.html that it cannot resolve to some masters and then send back the answer. I do not know yet how to do, but the important thing here is that it is no squid problem. Thanks again for your tip.

It includes codes from IETF internet standards, other IETF RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).
