What is Privacy Shield?

Warning: masking HTTP Headers can cause some web sites to break. Privacy Shield is intended for advanced users only.

Privacy Shield is an advanced HTTP filtering plug-in for the Internet Explorer browser. Built with your privacy in mind, Privacy Shield filters information as it being passed on by your browser, removing or masking sensitive data when found.

It's an unknown fact that when you surf the web your browser sends out information about your browser, system and internet connection. This information is called HTTP Headers that can contain information that is commonly used by marketers and statistical analysis programs. Privacy Shield can be configured in the Control Panel to remove / mask several such HTTP Headers:

Accept-Encoding

The Accept-Encoding field can be used to restricts the content-codings that are acceptable in the response. If an Accept-Encoding field is present in a request, and if the server cannot send a response which is acceptable according to the Accept-Encoding header, then the server SHOULD send an error response with the 406 (Not Acceptable) status code. If no Accept-Encoding field is present in a request, the server MAY assume that the client will accept any content coding. In this case, if "identity" is one of the available content-codings, then the server SHOULD use the "identity" content-coding, unless it has additional information that a different content-coding is meaningful to the client.

Accept-Language

The Accept-Language field can be used to restricts the set of natural languages that are preferred as a response to the request. If no language- range in the field matches the tag, the language quality factor assigned is 0. If no Accept-Language header is present in the request, the server SHOULD assume that all languages are equally acceptable. If an Accept-Language header is present, then all languages which are assigned a quality factor greater than 0 are acceptable.

Add Random Header

Sends a random HTTP header to the web server. Validity of the defined HTTP headers is not checked by the server but does confuse log analysis, and may cause custom applications to break.

User-Agent

The User-Agent request-header field contains information about the user agent originating the request. This is for statistical purposes, the tracing of protocol violations, and automated recognition of user agents for the sake of tailoring responses to avoid particular user agent limitations. User agents SHOULD include this field with requests. The field can contain multiple product tokens and comments identifying the agent and any subproducts which form a significant part of the user agent. By convention, the product tokens are listed in order of their significance for identifying the application.

Referrer Header

The Referer[sic] request-header field allows the client to specify, for the server's benefit, the address (URI) of the resource from which the Request-URI was obtained (the "referrer", although the header field is misspelled.) The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. It also allows obsolete or mistyped links to be traced for maintenance.
