以mod_wsgi + python为后端的apache服务器，我如何能够通知我的连接状态？

Question

i'm trying to build a web server using apache as the http server, mod_wsgi + python as the logic handler, the server was supposed to handler long request without returning, meaning i want to keep writing stuff into this request. the problem is, when the link is broken, the socket is in a CLOSE_WAIT status, apache will NOT notify my python program, which means, i have to write something to get an exception, says the link is broken, but those messages were lost and can't be restored.

i tried to get the socket status before writing through /proc/net/tcp, but it could not prevent a quick connect/break connection.

anybody has any ideas, please help, very much thanks in advance!

You cant. It is a limitation of the API defined by the WSGI specification. So, nothing to do with Apache or mod_wsgi really as you will have the same issue with any WSGI server if you follow the WSGI specification.

If you search through the mod_wsgi mailing list on Google Groups you will find a number of discussions about this sort of problem in the past.
