Also testing different ways to make choices available
tricky in receive cookies means, that `Cookie:' is sent to the client only if it is coming from the same host that the page being viewed.
For avoiding some kind of censorship, used hyperlinks can be scrambled with 2 methods: `rot13' is simple known routine. Method `tricky' uses a bit more complicated 3-way encoding-decoding method, which is difficult to notice by sensoring party (and the encoding constants used can be easliy changed in new httpgate releases).
Stopping GIF animations means, that incoming image/gif stream is checked and a significant information which tells that it is an animated gif is modified (I hope this is possible?)
The option of not sending host information is there that the behaviour of a web server can be tested.
