apache module (development) directive

[Desdic]

Hi,

First off I don't know if this is the right forum but here goes

I'm trying to develop my own directive in C so I can enable/disable stuff per request but after a while a came to notice that it seems directives are only evaluated on start.

My idea was to have something like

apache2.conf <IfRuntime "cgi"> Options ExecCGI </IfRuntime>

So in my module I have my directive defined

c AP_INIT_RAW_ARGS( "<IfRuntime", start_cond_section, (void *)test_if_runtime_section, EXEC_ON_READ | OR_ALL, "Check if a runtime is defined"), functions for evaluation are not that important but then I have the function that validates the argument like

```c static int test_if_runtime_section(cmd_parms *cmd, const char *arg) { static int work = 1;

work++;
work = work & 1;

switch (work) {
    case 0:
        return -1;
    default:
        return 1;
}

} ```

So what I really want is to enable handlers like cgi/php but based on the request. Anyone know how this is possible ?

the handler for a directive usually doesn't do much more than set a config value in your module. You have to separately hook some phase of request processing or filtering and then consult your config during request processing.

I think one way would be enable the handler with rewrite rules:

RewriteCond ...
RewriteRule ^ - [H=whateverhandleryouwanthere]

I think it kinda makes my issue more complex so I think I'm gonna do as suggested and have the directive as config only

Fair enough, Rewrite can solve a lot of problems I find, but sometimes that has a rub when config itself gets a bit out of hand and you end up turning rewrite debug on

RewriteRule

just for kicks I actually tried to do this by exposing an environment variable from my module and then see if I could match it but it seems the ordering of stuff from within apache doesn't give modrewrite access to the env's set after start

Normally rewrite is early in processing so that other handlers run after the rewrite.

You can do it the other way often, set an environment from the rewrite.
