Hi, I'm running Apache/2.0.52 as a reverse proxy on a RHE4 box, the backend app server is on a separate machine again RHE4, running Apache/2.0.52 and mod_perl 1.99_16.
There are intermittent 502 responses being generated by the proxy although a page refresh generally resolves the issue, we are trying to get a configuration of 2 RP boxes in front of 3 mod_perl app servers into production but will need to understand / resolve the issue of these intermittent 502 responses first.

Note at this point I'm using mod_rewrite [P] to proxy the requests to the app server rather than using ProxyPass as we have many rewrites in the conf. I've googled around and have seen that others have observed similar scenarios when using this setup in Apache 2.0 but have not seen anything specific about a resolution or path to resolution. Your help gratefully appreciated. Kind regards, Cris Cristian Pini Foresite Business Solutions Ltd Tel: 020 8540 0040 Direct: 020 8545 6813 http://www.fsite.com
