http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23899 Header Expect: 100 and mod_rewrite and mod_gzip (not zipping) Summary: Header Expect: 100 and mod_rewrite and mod_gzip (not zipping) Product: Apache httpd-1.3 Version: 1.3.27 Platform: Other OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: mod_rewrite AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] If the Expect: 100-continue header is passed in a request to the apache server which has mod_rewrite configured to forward the request to an IIS server the resulting page is never zipped by mod_gzip. Removing the Expect: 100 header returns a zipped page. The mod_gzip log looks like this. Successful zip 10.254.33.174 - - [16/Oct/2003:18:10:24 -0700] "qagateway01.qa.myco.com POST /ws/api.dll HTTP/1.1" 200 477 mod_gzip: OK In:1258 -< Out:262 = 80 pct. Unsuccessful zip 10.254.33.174 - - [16/Oct/2003:18:54:32 -0700] "qagateway01.qa.myco.com POST /ws/api.dll HTTP/1.1" 200 1480 mod_gzip: SEND_AS_IS:NO_200 In:0 -< Out:0 = 0 pct. The headers in the unsuccessful response look like this. It's difficult to tell if both headers are part of the same response. HTTP/1.1 100 Continue HTTP/1.1 200 OK Date: Fri, 17 Oct 2003 01:30:18 GMT Server: Microsoft-IIS/4.0 Content-Type: text/xml Content-length: 1258 X-Cache: MISS from qagateway01.qa.ebay.com Connection: close The request is also zipped if mod_rewrite is removed from the equation regardless of the Expect: 100-continue header. Unfortunately Expect: 100-continue is required in MS .Net httpwebrequest class but I was also able to replicate this bug with a perl script. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
