I am trying to redirect PUT request for a specific endpoint to another host.
The said endpoint resides under /internal and accepts only PUT requests. The other endpoints under /internal will continue to be served by my main host/server.
I have tried setting it up using both rewrite rules and using the proxy ([P]) flag and using the ProxyPass directive - all resulting in a 500 Internal Server Error and the request never makes it to the new host
My client application uses a simple REST client that cannot handle redirects, so I have to use some kind of proxying.
Apache logs show the following
[Thu Feb 10 08:56:20.394444 2022] [rewrite:trace1] [pid 8579] mod_rewrite.c(480): [client XXX.XXX.XXX.XXX:XXXXX] XXX.XXX.XXX.XXX - - [subdomain1.mydomain.com/sid#55d4ed07ecb0][rid#55d4ed2c5f20/initial] go-ahead with proxy request proxy: https://subdomain2.mydomain.com/internal/my-endpoint [OK] Here's the current configuration for the specific vhost
