How to check what are the modules compiled into the binaries in a package?

[akhran]

Eg. I have apache2 installed. How do I check if mod_proxy module has been compiled into the web server or if the module is available to be dynamically loaded?

In general, how do we go about checking if a particular module has been compiled into the binaries in the packages available in the repositaries?

Thanks !

apache2 -l should list the compiled modules

apache2 --help should show other available commands

apache2 -l does work but apache2 --help gives the message
'(9Address already in use: make_sock: could not bind to address [::]:80
no listening sockets available, shutting down
Unable to open logs'

In general, is there a standard command/parameter that can be used to display the list of compiled modules for a binary, say postfix?

Thanks !
