Anonymous/private HTTP alternative.
I request that the Tor project creates a new private protocol replacement for HTTP.
HTTP is bloated, full of features preventing privacy and anonymity. Examples include request headers, cookies, referrer, etc.
Tor and other anonymity and privacy tools try to work around these issues, but it's a whack-a-mole game.
This new private protocol shall be a scaled-down version of HTTP, with any anonymity-hostile features removed. In fact it shall be minimal: having only the absolute minimum number of features that still allow basic web browsing.
It is important that the protocol is designed by a trustworthy party, such as the Tor project, and not by any commercial parties. Said commercial parties are in fact currently working on HTTP protocol replacements, however user tracking and lack of privacy and anonymity is in their interest, as it supports their business model.
Examples of problems that need to be addressed:
Request headers, such as HTTP_ACCEPT headers are a user-tracking feature, are not needed and shall be absent.
Request method (GET, POST, etc.): minimal design dictates that only one (HTTP GET-equivalent) method shall suffice.
URL: To prevent user tracking in form of casing, the URL shall be lower-cased before a request is sent. The URL can be rendered with mixed case to the user for readability of course.
Encryption: All requests must be encrypted with a predefined (not negotiated) scheme.
No form of negotiation can take place between the client and server, including: compression, natural language, protocol versions, etc.
The client must not identify itself in any way.
Etc. Many other issues probably remain, of which I have no knowledge. That's why I turn to the Tor project, as your community is best-suited to identify and address other privacy issues with HTTP.
To ease adoption, the new protocol could resemble technically HTTP as much as possible, so that minimal development is needed in software (clients, servers) to provide support.
I can only hope that Tor community will accept this challenge.
