Re: [users@httpd] 200 OK for a network error?
Hi, Thank you for your comment. I tried Apache 2.4.9 + mod_proxy_ajp + Tomcat 6.0.35. But, unfortunately HTTP status codes were the same ones. (Apache HTTP status = 200, Tomcat's = 500.) Apache 2.2.x + Tomcat 6.0.35 behaves so, too. Next, I tried with Apache 2.2.15 (2.4.9) + mod_proxy_http (not ajp) + Tomcat 6.0.35, uploading a large-sized file and switching off network of the client machine while waiting HTTP response. At that time, the Apache HTTP status was 400, and Tomcat's one was 500. It seems more suitable for me because 400 means a kind of client error. Is it violated by AJP or RFC specification that the ajp's HTTP status 200 in such a network error? Hello, I think this has been fixed in 2.4.8 with this changelog: *) core: Detect incomplete request and response bodies, log an error and forward it to the underlying filters. PR 55475 [Yann Ylavic] A backport is proposed for next 2.2.x release and is waiting for approvals. I will update the bugzilla https://issues.apache.org/bugzilla/show_bug.cgi?id=55475 about this. Please note that with this fix the HTTP status returned to the client (and logued) will be 408 (Request Timeout).
