web site synch/publishing/via proxy tool - any ideas?

Hi,

Question - Anyone know of a ruby tool that does this? (or something close to it)...or else http/web libraries that might be a good start to building this if nothing exists? (or even a non-ruby tool if you know of it)?

Requirements * Sync specific intranet web pages specified to an online (external) site * Specific pages in the form of URLs (e.g. latest team contact details) * Program periodically checks for new/changed content and then downloads content (that page & direct images etc) to an external site * Has proxy settings (host, port, username, password) to access Internet (from a work location) to synch out * re where/how it stores this, and whether protected/open, I'll leave this open - would be preferable to require credentials to access via internet (when not at the work location)

Thanks
