Some browsers are capable of requesting data from a web server to be returned "compressed". They do so by including an HTTP field of the following form in the request: "Accept-Encoding: gzip". The pages returned are not plain text but are in a specially encoded compressed format. Outpost does not support decompression of compressed pages on the fly, so it disables compression by stripping any "Accept-Encoding: gzip" field from each browser's request.
If you want to enable page compression run Regedit from the command line and set the "Enablegzipencoding" key value in HKEY_LOCAL_MACHINE\SOFTWARE\Agnitum\Outpost Firewall to 1. However, please note that the Ads, Content and Active Content plug-ins will not work for sites that use compression.
Note:
- If you use Outpost Firewall Pro 4.0 or Outpost Security Suite Pro 2007, disable self-protection before changing the registry.
- Products version 6.0 and newer completely support page compression (gzip compression).
