If anybody wants my very immature load balancer written in C#:


Now featuring an HTTP header class which parses headers, replaces headers, retrieves headers, etc.

So the load balancer now replaces/sends along the X-Forwarded-For header to the back end, and always does Connection: close, and always does HTTP/1.0 to the backend. (wanting to avoid dealing with chunking for now)

Things to do:

-- support POSTs (only GET works now)
-- limit max incoming header length
-- limit global proxy to client buffer size
-- limit max pending connections
-- limit per-connection proxy to client buffer size
-- wait for bugs.ximian.com and make sure some variation of my socket patch gets committed
-- make the load balancer be more of a usable object itself, letting clients set its listening port, backend node selector manager, limits, etc.
-- make a front-end which parses command-line args and inits the load balancer.
-- write a node selector to listen to LJ's broadcast messages and do random weighted selections.
-- write some stupid node selector subclasses as demos
-- proper C#-style docs
-- timeouts everywhere
-- management/stats port.
-- tons of testing
-- put it in limited production somehow and make it take a beating. :-)

What are you using to learn C#? Just some online documentation or a book?

To learn it. But it's also a very cool language.

good enough to make LJ run on it ? I am just curious.. I know the framework looks nice but does it scale ? high performance ?

Is it HTTP 1.1 or 1.0?

Looks like HTTP 1.0. That certainly saves you a lot of grief.

I'll do HTTP/1.1 later, perhaps.
