Subject Re: [users@httpd] Control / Modify the HTTP Status Line

Hi matt and lbutlr
Thanks for the response.

I guess I should add few pieces of information.
The client is one SaaS and the backend is another SaaS. The backend returns
302 which is right but the client consider anything which is not 2xx as
error which cause it to retry.

Therefore I must "hack" or stitch it with a proxy. I am using mod_proxy.
My other alternative is to use other software than httpd to stitch those
two services and show 200 instead of the 302.

The solution mentioned in stackoverflow will not work for 302 response as I
cannot set error page for such non-error response codes.

The solution with rewrite won't work neither as I need to alter the
response and not the request.
