Most of the time, FastCGI works fine. However, every few page views in a while it returns the following error page (I'm copying the page's source). Notice the HTTP headers were printed in the error page - FastCGI apparently mistakenly thought they were part of the actual content: HTTP/1.1 200 OK Date: Sun, 14 May 2000 07:26:23 GMT Server: Apache/1.3.11 (Unix) mod_ssl/2.5.0 OpenSSL/0.9.4 mod_fastcgi/2.2.3-SNAP-Apr29-17.29 PHP/3.0.14 X-Powered-By: Zope (www.zope.org), Python (www.python.org) Content-Length: 6669 Connection: close Content-Type: text/html <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <HTML><HEAD> <TITLE>200 OK</TITLE> </HEAD><BODY> <H1>OK</H1> The server encountered an internal error or misconfiguration and was unable to complete your request.<P> Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.<P> More information about this error may be available in the server error log.<P> <HR> <ADDRESS>Apache/1.3.11 Server at www.example.com Port 80</ADDRESS> </BODY></HTML> and the logs say: [Sun May 14 02:26:20 2000] [error] [client 212.29.231.2] FastCGI: comm with server "/Services/www/website/zope" aborted: protocol error: invalid version: 73 != FCGI_VERSION(1) [Sun May 14 02:26:23 2000] [error] [client 212.29.231.2] FastCGI: comm with server "/Services/www/website/zope" aborted: protocol error: invalid version: 110 != FCGI_VERSION(1) -- Itamar S.T. itamar@maxnm.com
