Hi all, i was wondering if anybody could help me with this issue. I am trying to create an update tool within c++ which checks the download webpage file to see if it has been updated since the last recorded date. My problem is that i have no idea where to start with this (don't know how to get the timestamp of a file within c++ specifically of a remote file via http). Help anyone? Have no code yet.

Look for "Last-Modified"

Just because you ask for "foo.html" from some server, that does not mean there is a file called foo.html on the remote machine.

Many complex websites generate content on the fly from some database, so the concept of "age" might take on some rather esoteric meaning.
