Hi, I encountered a problem after upgrading Apache to 2.2.15. The client will be stuck and load infinitely via the HTTP protocol, but it worked correctly in 2.0.55 before I upgraded.
I tried to sniffer the packet, and found 1. If the page size is larger, most of the page and http header will be received in the client but the last chunk won't be sent out from the Apache. 2. If the page size is small, the client only can see the http header. It seems that some packets are queued in the Apache, ..?! I describe the process as below, 1. Client send http request to the server, http://myhost/web.cgi, the cgi is implemented in GNU CGI which has been dead since 2002. 2. web.cgi fetches the login.html file and sends back to the client. 3. The client gets stuck... There are some things weird: 1. When I remove the directive "Listen 443" or "Keepalive On", then the HTTP can work correctly via "Listen 80" without stall. 2. If both the "Listen 443" and "Listen 80" are enabled, only the HTTPS can work. HTTP will have the problem I just mentioned. Do you guys have any idea about my problem? Why the behavior of dealing with output file is different between HTTP and HTTPS protocol?
