I need a technique for executing very fast code behind the httpd

Hello all.

Question: Is it any way possible to access through the httpd server
resources like objects or remote procedures that run on the server in binary
form and dont get disposed after each call of the resources?

I read lately alot about cgi and the apache server but i haven't found an
answer for what I'm looking for. I developed a small "program" (script) in
javascript that runs local in each browser. I also can comunicate with a
http server via ajax form within the browsers and ask for resouces. Now I
need a way to create on the serverside a program that builds up compiled
objects that can read each other properties and running in an semi-endless
loop, it also has to run very fast, but it seems i miss the technologie for
this.

Lets think about it like in each browser we have players of a game. So we
have in each browser an object with properties x,y as coordinates. I can
post via ajax to the server if on the client a directional key is pressed.
The server has to compute the new position and reply back to the client its
new position but not only its new position cause the server has to reply
also the computed coordinates of the other objects so he needs at least read
the coordinates of the other objects. So there can be around 25 requests/s
from a browser (thats not the problem). The other problem is the server
program has to run in an endless loop until only a player remains alive. And
the last problem is that the program has to run fast because on the server i
need to do collision detection etc.

I hope you guys and girls can help me with some advises of how i can do this
via the httpd server or point me to some other tehnologies that could solve
my problems.

Thanks.

I figure SOAP might be what you need.

I thought about using soap as an comunication protocol but in fact the
remote procedures are php scripts or asp i need compiled code that can
execute fast and share objects, the communication protocol isnt important it
can be anything.

CORBA offers a framework for client server
communication. In linux omniorb implements
CORBA standard, but I don't know how to integrate
this with apache.

We have implemented ONC-RPC (a/k/a SunRPC) in PHP and modified the
rpcgen compiler to output PHP stubs. We use that in a setup like this:

client <--HTTP--> Apache with mod_php <--RPC--> native daemon

One team maintains the native daemon and another maintains the PHP code
facing the client. We just share the .x file describing the interface.

It performs well, and is very easy to maintain.

If you are interested, we are willing to share the code. It's not very
much, but it does the job perfectly.

Best regards,
Morten

This sounds something that I'm interested in i mean onc-rpc implemented in
php and this could solve my problem. I would like to also help you guys if
its that what I'm thinking about. If you could share the code it would be
more than what i was asking for and i appreciate it alot.

Common CGI can be used for this, but its speed is not very good because on
each request the server must run the interpreter in a new process and this
takes time.

You can use technologies like mod_perl or fastcgi to do this. A mod_perl
handler starts when the server starts and ends when you stop/restart the web
server. It has the Perl code loaded in the memory, parsed and compiled so it
just waits for the requests.

A fastcgi program uses the same technology, but it doesn't depend on Apache.
It can run under Apache, Nginx, lighttpd...

The mod_perl handlers should be written in Perl. fastcgi can run programs
written not only in perl, but in many other languages, so it is more
flexible.

Some users say that fastcgi is prefered, although I couldn't make a program
to run as fast as when using it with mod_perl.

Sure. You can implement your choice of protocol in a module, either
as a content handler from scratch, or as a mod_proxy backend.

Or you can use a protocol apache already supports: CGI and FastCGI
are simple glue to your own programs, or if your program supports
(say) HTTP or AJP you could just use the proxy.

FastCGI might be a simple fix for that sort of thing.

Have you looked at Tomcat? Java(J2EE) seems to be fast enough for
almost everybody...

Thanks all. I will test some of the things you told me in here and will give
feedback in case i will find a good solution. Second I'm thinking to test
the mod_perl solution and if this isn't working i will write maybe my own
module for apache. The ONC-RPC from PHP to another deamon could also be a
solution and I started to test that.

Write to you all later and thanks alot for the fast answers. You are all
great.
