Synopsis

SSLCacheServerPort file|port
Server config
Not available in Apache v2

The cache server can use either TCP/IP or Unix domain sockets. If the file or port argument is a number, then a TCP/IP port at that number is used; otherwise, it is assumed to be the path to use for a Unix domain socket.

Points to watch:

• If you use a number, make sure it is not a TCP socket that could be used by any other package. There is no magical way of doing this: you are supposed to know what you are doing. The command netstat -an | grep LISTEN will tell you what sockets are actually in use, but of course, others may be latent because the service that would use them is not actually running.

• If you opt for a Unix domain socket by quoting a path, make sure that the directory exists and has the appropriate permissions.

• The Unix domain socket will be called by the “filename” part of the path, but do not try to create it in advance, because you can’t. If you create a file there, you will prevent the socket forming properly.
