Another option you have is if you have an old machine and are somewhat tech inclined you can set up a Squid proxy and turn on anonymizing function. It does the following by default:
1. A HTTP request (V1.0) contains a header like an eMail does. MIME Headers are allowed.
2. A proxy is urged to resubmit the whole header to the requested system.
3. This resubmittment can be filtered. There are two methods of selecting or droping header lines.
1. Only header lines known to compromise privacy are filtered:
* Authorization: (Removed due to strong customer requests, password protected pages fail definitly)
* From:
* Referer:
* Server:
* User-Agent:
* WWW-Authenticate:
* Link:
2. Only header lines known to be secure are passed.
* GET
* POST
* HEAD
* Allow:
* Cache-control:
* Content-Encoding:
* Content-Length:
* Content-Type:
* Date:
* Expires:
* Host:
* If-Modified-Since:
* Last-Modified:
* Location:
* Pragma:
* Accept:
* Accept-Charset:
