Hey, Mr Sun ! Just because it is the holiday season doesn't mean that
you can be lazy, OK ? I worked through Xmas and it looks like New Year
too ! (Side note : Mr Sun and myself know each other...)

Yes, it is possible, BUT I do not think that your system administrator
will allow it. Speaking as a former sysadmin (albeit on NT), this
constitutes a breach of security. If you allow people access to even one
machine inside your private network (particularly if that machine is
serving public web pages and needs to be connected all the time), some
cracker will eventually find a way to break into the network and maybe
even your boss' files ! I know this sounds unlikely in the Singapore
context, but your sysadmin needs to cover his ass too !

On a pedantic note : Apache can be configured to act as your proxy
server, but it is neither secure
nor fast. Personally, I wouldn't use it as a proxy, unless I really,
REALLY have to. There are free proxies available on Linux and UNIX.

Well said, Jeff ! If you try to "find" a hole in your corporate network,
you'll be putting a lot of people's jobs in danger. I know what company
you work for, Mr Sun, and I'm sure they wouldn't like what you are
proposing to do ... :)
Happy New Year !
