Sometimes it's useful to use an instutional webcache from home - getting at things on IEEEXplore for example - but many webcaches don't allow access from the internet. SSH to the rescue.

Assuming you have access to a machine inside the institution, host.inst, and that the webcache is called webcache.inst on port 8080 then:

ssh host@inst -L 8000:webcache.inst:8080 -T

Will forward port 8000 on your local machine to port 8080 on the webcache, set up your browser to expect a wep proxy on localhost:8000.
