[Http-crcsync] Is the crcsync effort still alive?

[Alex Wulms]

Project is indeed a little bit asleep.

The Apache server and client modules are stable and usable. Though, the 
CRC-codec sub-module needs to be rewritten due to licensing reasons; the 
current implementation is GPL but we would like to have one that is LGPL 
or another license that allows inclusion of the entire stack into 
non-opensource software, in order to get widespread adoption. It's on my 
to-do list to rewrite the CRC-codec. But this re-write will *not* change 
the protocol. It's purely a technical rewrite for licensing reason like 
said above.

I have also understood from Martin a while ago that he was planning to 
include the Apache modules with the next version of the OLPC school 
server distribution, so that it can be piloted in the field. I don't 
know whats the current state of that effort.

The biggest performance gain will probably be achieved with the 
proxy-model, whereby multiple clients (e.g. pupils with XO laptops) are 
connecting to the same site (e.g. during a lesson on a certain subject), 
through the client-proxy. That is where you will get the biggest chance 
on page-re-use and delta-acceleration.

Nevertheless, on individual user level (e.g. with the client embedded in 
the browser) I do expect some advantages as well, especially when 
visiting multiple pages on the same site, like a news site or a 
discussion forum. It would indeed be great if this could be 
bench-marked. I did have this on my to-do list a while ago but it 
slipped a little bit through the cracks. My apologies for that.

Cheers,
Alex
