Centralizing outgoing two-way SSL connections

We are currently using Apache to handle incoming SSL requests. These are two-way SSL connections. Apache accepts the https connection and pass the request on as http connection to the application server. This works well for us.

We would like to use the same kind of centralized mechanism for outgoing two-way SSL connections. Is there a way do this with Apache or another product? To complicate things the client certificate needed to identify out client can vary depending on the destination.

In开发者_运维知识库 short: - Internal clients connect through http to Apache or another product. - Apache or another product knows based on a rule (?) that a two-way ssl connection is required and sets this up with the destination. - Depending on the destination the correct certificate is sent to identify our client.

What you're talking about is, or course, an HTTP proxy server. In the first scenario you are using it as a transparent proxy to provide SSL support for connections to a set of web pages. In the second scenario you want to use it to provide connections to secure-only pages on behalf of clients speaking HTTP.

You can do this with the Squid proxy, which is free and open-source, provided that your machine sits between the clients and the Internet. Look for "SSLBump". You do need a certificate which the clients would consider valid for all web pages to be accessed (otherwise they will notice what you are doing, which is basically a man-in-the-middle attack).

However, I would strongly recommend against this - if a site requires SSL, it is likely to do so for a reason. It is almost certainly not OK to have internal clients connecting to an online banking site and have you bumping down their encryption so that you can monitor their traffic or whatever...
