Proxy Issues (Apache Users)

Hello Everyone,

I'm having a bit of a struggle figuring out how to apply my _solution_ for this current issue I'm facing.

I have server A & server B that both need to reach an external service, server Z.

Server B has access while A does not, so we are wanting to make a proxy to mediate the requests from B -> Z for A.

I thought the curl command from Server A would be:

curl https://server-z.com --proxy http://server-b

But that gives the following error:

* Trying x.x.x.x...

* Connected to host.name (X.X.X.X) port 80 (#0)

* Establish HTTP proxy tunnel to server-z:443

> CONNECT server-z:443 HTTP/1.1

> Host: server-z:443

> User-Agent: curl/7.40.0

> Proxy-Connection: Keep-Alive

< HTTP/1.1 502 Proxy Error

< Date: Thu, 16 Jul 2015 22:40:16 GMT

< Server: Apache/2.4.12

< Content-Length: 383

< Content-Type: text/html; charset=iso-8859-1

* Received HTTP code 502 from proxy after CONNECT

* Closing connection 0

curl: (56) Received HTTP code 502 from proxy after CONNECT

For the current vhost configuration on server B(server-b.proxy), I am using:

ProxyPass / https://server-z

ProxyPassReverse / https://server-z

From Server B, I can run:

curl http://server-b.proxy

Which works/mediates, but I'm pretty sure this is incorrect as when I try it from Server A, timeout as per usual occurs. Also, the curl request is made though a PHP wrapper which disables verification for the ssl request(not sure if it matters or would be brought up).

From what I understood I needed a reverse proxy since I wanted this on a fixed url, but now I'm not so sure. Any clarity on what I'm doing wrong would be much appreciated.

Thanks,

Matthew
