What are the ProxyPass system requirements?
The ProxyPass software augments the security of existing Apache authentication and authorization modules. Please note that ProxyPass does not do the password authentication/authorization control itself; rather it works in conjunction with your existing setup. It is compatible with standard and custom modules (e.g. mod_auth, mod_auth_db[m], mod_auth_mysql) that use Apache access, authentication, and authorization control phases. One of these modules must be installed and configured. ProxyPass also requires a UNIX-based, Apache 1.3.x or 2.x server enabled with dynamic shared object support (DSO mod_so.c). ProxyPass has been deployed successfully on many UNIX flavors in both 32bit and 64bit architectures. Of course, the ProxyPass system also requires money.
