Hello, I am seeing entries like below quite frequently. It looks to me as if the Content-Language and Content-Location headers are not parsed correctly, since I cannot see this stuff in the traffic going to the squid. In this config Squid has a WebWasher installation as parent and has an imagefilter as ICAP-respmod. 2008/10/20 10:52:15| WARNING: unparseable HTTP header field {Content-Language123453} 2008/10/20 10:52:15| in {Accept-Ranges: bytes Cache-Control: max-age=31536000 Content-Language123453 Content-Type: image/png Date: Mon, 20 Oct 2008 08:52:14 GMT Expires: Tue, 20 Oct 2009 08:52:14 GMT Last-Modified: Fri, 12 Sep 2008 19:34:25 GMT Proxy-Connection: close Server: Apache } 2008/10/20 10:52:15| WARNING: unparseable HTTP header field {Content-Language34536} 2008/10/20 10:52:15| in {Accept-Ranges: bytes Cache-Control: max-age=31536000 Content-Language34536 Content-Type: image/png Date: Mon, 20 Oct 2008 08:52:15 GMT Expires: Tue, 20 Oct 2009 08:52:15 GMT Last-Modified: Fri, 12 Sep 2008 19:34:25 GMT Proxy-Connection: close Server: Apache } 2008/10/20 08:18:18| WARNING: unparseable HTTP header field {Content-Location107028} 2008/10/20 08:18:18| in {Accept-Ranges: bytes Content-Length: 107028 Content-Location107028 Content-Type: image/jpeg Date: Mon, 20 Oct 2008 06:18:18 GMT ETag: "923c75aa5230c91:237d" Last-Modified: Fri, 17 Oct 2008 12:19:56 GMT Proxy-Connection: keep-alive Server: Microsoft-IIS/6.0 Via: 1.1 webwasher (Webwasher 6.8.2.3889) X-Powered-By: ASP.NET }
