Tests for the CVE-2011-3368 (Reverse Proxy Bypass) vulnerability in Apache HTTP server's reverse proxy mode. The script will run 3 tests:
- the loopback test, with 3 payloads to handle different rewrite rules
- the internal hosts test. According to Contextis, we expect a delay before a server error.
- The external website test. This does not mean that you can reach a LAN ip, but this is a relevant issue anyway.
