Proxy Servers and Content filtering

Today we talked about Proxy Servers and their uses. Most home computers will not have a proxy server due the cost factor. When using a proxy server the initial user may have to wait a few moments until the server finds the requested page and uploads it to the computer that has made the request. It will then put a copy of the page into it's memory and all subsequent requests for that page will load much quicker due to it being in the memory.

There are many different types of proxy's and the cost of having one run can be prohibitive.

We also talked about Content Filters and their uses.
Content filtering is the technique whereby content is blocked or allowed based on analysis of its content, rather than its source or other criteria. It is most widely used on the Internet to filter email and web access. When surfing the Web a content filter can be employed to filter out any information deemed unsuitable for the people using the computers.
