Some errors

[Hannie Dumoleyn]

Found in ubuntu-docs Precise (string 1577 in Launchpad).

A <em>web proxy</em> filters websites that you look at, it receipts 
requests
from your web browser to fetches the web pages and their elements, and
following a policy will decide to pass them you back. They are commonly 
used
in businesses and at public wireless hotspots to control what websites you
can look at, prevent you from accessing the internet without logging in, or
to do security checks on websites.

..it receipts.. I think this should be ..it receives..
..to fetches.. This should be to ..fetch..

Please do not change this in the current file in Launchpad, but add it 
to a list of errors that need correction. At a later date they can be 
added to the pot file.
