If you are talking about uploading files to your Apache server, there are several options. Perhaps, the easiest, is a little php application. To achieve this you would have to add php support to your Apache and write some code. A little Google search pointed me to, for instance:
PHP File Upload
Which may meet your needs.
Other option is to configure mod_dav (DAV extensions to HTTP) on your apache. Have a look at:
mod_dav: a DAV module for Apache
I personally prefer PHP, though both systems could be potentially dangerous...
