http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18157 Proxy Buffering Disrupts Staged Response Delivery Summary: Proxy Buffering Disrupts Staged Response Delivery Product: Apache httpd-1.3 Version: 1.3.27 Platform: All OS/Version: Other Status: NEW Severity: Minor Priority: Other Component: mod_proxy AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] Using mod_proxy as a reverse proxy we discovered that buffering was collecting staged "update" messages for a long lived process and delivering several at once. This disrupted the response as it was staged to give updates to the browser to keep the connection alive, preventing a "Document contains no data" type error. The problem was tracked to the fact that mod_proxy's ProxyIOBufferSize ignores values less than 8192 bytes, also ap_bwrite in buff.c will buffer responses when using mod_proxy. I have a patch to allow less than 8192 in ProxyIOBufferSize and to allow the presence of a "X-Buffer-Output" header set to "no" to unset the B_WR flag in the response to the browser. I will attach this patch as an update to this bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
