Is it possible to build apache http server as a in-process module?
Hi, all
I would like to adopt apache http server in my project. But it is
necessary for the http server to be an in-process module to be plugged in
the current system. That is, I would make a little modification to the make
file and build the httpd as a dll/so and export the main method for other
modules to reference. But would it lead to some side-effect?
Thank you in advance.

... or write your own webserver to do what you want? Python has a nice
shell of one built right in!

Might an alternative for you be to use apache as a proxy, and
just write a proxy protocol module to communicate with your
original application? You might take the way mod_proxy_ajp
communicates with a java appserver as a model for that.

Thank you, I would like to have a try of the module.

This isn't close to a users@ list question. There is also a modules-dev
mailing list at the httpd project which discusses the c language sources,
the API and is more in tune with what you are asking.
You would want to look at one of the MPM implementations under server/mpm/
and replace/revise it to run in process. It's a non-trivial exercise but
certainly is possible.

Thank you for your answer, Morgan.
What I want to do is to plugin an in-process http server module in an
exsiting product to expose its original functionality as web service
(soap over http). :) Since the existing product is already an executable
one so it seems that the only choice is to write an apache module to
communicate with apache http server and the existing product by IPC...
I know there are in-process http server in java but I would not like to
add the burdon of an additional JVM and the cost of JNI calls so I am now
looking for an in-process http server in native language.

Short answer: its not possible
Long Answer: Its not possible because apache was designed as a
stand-alone HTTPd.
Simple solution: write a way for your app to talk to Apache. I.e. write
a Module that mubmles between your app and apache when it gets a request
of some kind that it likes.
Past that, why would you want to do what you're talking about?
