Topic: Redirects

[LOB99]

Hi all,

Fairly new to Apache and redirects and I'm having a hard time accomplishing what I need to do.

Basically, we need to call a URL from Server A that resides on Server B. Server B needs to redirect the traffic to Server C, but it needs to look like the traffic originated from Server B, not Server A. Server B is where Apache resides. Server A resides in a large datacenter and we cannot predict the IP the traffic will come from, and the 3rd party that hosts Server C did not feel comfortable whitelisting entire blocks of public IPs.

All we are really using this particular Apache server for is rewriting traffic to backend servers, as well as external servers. The external redirect is what is not working properly.

So, the best way I have found is by using ProxyPass in ssl.conf. Works perfectly, but the traffic looks like it originated from Server A and Server A is not whitelisted for the reasons stated above.

This is what I want:

Server A calls https://mysite.com/url and is redirected to https://theirsite.com/url.

This is what is in ssl.conf:

ProxyPass "/url" "https://theirsite.com/url
ProxyPassReverse "/url" "https://thiersite.com/url"

The above works perfectly, but it looks like the traffic originated from Server A. What am I doing wrong?

That is because of the reverse proxy situtation. mod_remoteip can help to fix that issue. On Linux there is also mod_rpaf available.
