Hello:
I'm quite new to Apache custom modules, and I have a doubt about having two custom modules to parse the same petition.

First of all, I'm working on Apache/2.4.38 (Raspbian).

Now, let me explain a bit better.

Currenlty I have a custom module that parses every ".calc" petition, so ".../anything.calc" will trigger "calc-handler"

On my .htaccess, I wrote "AddHandler calc-handler .calc" to allow it.

Now, I want to allow acces to another handler that triggers on each server petition, so, let's say...

a) Client request "page1.php", so "general-handler" gets the petition, makes it's process, then the php page it's parsed

b) Client request "anything.calc", so "general-handler" gets the petition, make it's process, then "calc-handler" triggers and makes it's process.

I made a very simple handler, really simillar to the one defined on http://people.apache.org/~humbedooh/mods/examples/mod_example_1.c, but changing

- omit "if (!r->handler || strcmp(r->handler, "example-handler")) return (DECLINED);"

- use "SetHandler" instead of "AddHandler"

The result is that "general-handler" triggers, but then I see no response from "calc-handler".

Is there anything I'm doing wrong? Both modules have definitions of AP_MODULE_DECLARE_DATA and register_hooks in simillar way that the apache web example (so maybe there's something to change there?)


Thanks in advance!

Hello

As said on this same forum I just followed a similar way done in https://stackoverflow.com/questions/11097096/ensure-execution-order-of-two-apache-filters, and worked fine.

I had to remove the "Sethandler", and it worked.

Thanks.
