Subject [users@httpd] Reverse SSL Proxy in cluster Configuration
Date Tue, 20 Oct 2009 09:15:35 GMT
Hi all,

    We're trying to mount a reverse proxy cluster using two apache 
severs (httpd v2.2.14) balanced by a hardware load balancer (CISCO). 
This balancer distribute the incoming requests to each reverse proxy. 
The implented system seems to work well with most of the applications 
but we have found some problems with an SSL application when somebody 
wants to upload files: the error 413 use to appears (not always): 
Request Entity Too Large. We have no clue about the problem. The thing 
is with only one server active of the cluster the application works 
perfectly.
The configuration is shared between proxys and the reverse-proxy is 
implemented using name virtual hosts.

Any idea?

Regards,

Regards,

Manuel Vicente.
