I have several webapps that do a significant amount of recursive loads
of snippits of HTML utilizing XHR/http/ajax requests. These apps are all
debugged and in production. The server has no problem whatsoever in
keeping up with the multiple concurrent requests. However, the
open-connection limits on the browsers that block more than 6 concurrent
connections to a server is killing me in performance.
I've been looking into WebSockets which I understand does not incur the
wrath of the browsers when I have a need for more than 6 concurrent
connections. I have no problem making a move to WebSockets if that
will indeed help performance. However, I have literally many hundreds
of JSPs that are coded, tested, and working. So I'd like to minimize
the rip-up to the JSPs.
I've googled around trying to find answers about how (if) I can invoke
JSPs via WebSockets. From what I can tell, it appears it's possible.
But no straightforward explanation. A WebSocket servlet extends
"WebSocketServlet", correct? But JSPs extend HTTPServlet, at least by
default, correct. So that seems like an fairly big immediate problem.
Do I need to do some gyrations like writing a WebSocket router servlet
object that turns around and creates/invokes a normal http call to
invoke the desired JSP? (BTW... I don't need any of the bi-directional
capabilities of WebSockets currently.... simply an "http emulator"
functionality for now).
I guess I could get multiple IP addresses for the server and set up
multiple secondary domain names to 'fool' the browsers into thinking the
requests aren't all going to the same server thereby getting 6 requests
per 'server'. But at best that's a total hack, and not an inviting
solution.
Any other suggestions (short of changing up the architecture to no
longer require multiple concurrent loads) will be welcomed. Likewise,
and corrections to any errant assumptions I have made so far are also
welcome.
Thx.
