I'd first determine which of the above possibilities it is.

Your computer: empty your cache.

To see if it's the webserver, let someone on a different continent
look at a certain page, then upload a changed version, and let that
someone check if changes are applied. If yes, then you can eliminate
the webserver.

For the proxy in your LAN: can't you bypass it to check?
