Interaction between modules....

[Devender Reddy <mu...@gmail.com>]

I had written an Apache Module, which will do some kind of parsing on the
user entered POST variables and then talks to Server Y. Following are the
things that I had done for this.

1) Gets the user entered inputs like name, age etc. Along with this, I will
also get a hidden variable "hide"
2) In my module, I will do the parsing, in such a way that the hidden
variable "hide" will be stored in my module and name and age will be passed
to the remote server(say Y) and my modules is sitting in server X.
3) Depending upon the parameters, the remote server Y will return me some
response.
4) Now I have to append this response to my stored hidden variable. let us
call this data DATA. (Upto here,  I had done without no problems.)


Now I want to pass this DATA(response+hide) to PHP module to the server X(
where my module is sitting).

in one way, I can say, once my module gets some response, then how do we
pass this response to the PHP module.

Thanks in advance for doing this favor.

You can actually hack it by hijacking the request, and running
the 'original' request as a subrequest.  It's ugly, but it works.

(Agreed, filters are by far the single most important advance
in Apache 2).

Filters are actually _the_ reason to use 2. The best thing you can do is
read the POST parameters during an early request phase an pass the new
values as GET parameters (POST is read from stdin and can't be read
twice).

Thats true, this looks like an input filter. But filters are supported only
in Apache 2.x version and currently my apache version is 1.3. Most probably,
we may not be upgrading to apache 2.0 in the near future.

So, it would be great, if you can let me know the equivalent functanality of
filters in apache 1.3.

Thanks & Regards

This looks like a job for an input filter. If your module is an input
filter, that changes the POST data, your PHP simply has to handle a POST
request.
