Re: Change Request-Header before mod_rewrite
Thank you very much!
That worked fine for me.
Now I got another problem. If I enable my module and call it up with
"localhost" in my browser a 404 is returned although there is a index.html in
the root directory of the webserver. If I disable my module and call it up with
"localhost" the index.html ist presented in the browser. So whats the problem
with my module?
The configuration of my module is the following:
SetHandler example-handler

Hi all,
I just developed my first apache module following the tutorial on the apache
website. The module is responsible for adding one header value to the active
request which must be checked in a mod_rewrite ReWriteCondition.
The problem is, that this value never reaches the mod_rewrite Rule. The Header
just behaves the same as the original request. Does anyone know why? What am I
doing wrong?
My module looks like this:
static int helloworld_handler(request_rec* r){
if (!r->main) {
apr_table_setn(r->headers_in, "X-CUSTOM-HEADER", "1");
}
return DECLINED;
}
static void register_hooks(apr_pool_t* pool){
ap_hook_handler(helloworld_handler, NULL, NULL, APR_HOOK_FIRST);
}
module AP_MODULE_DECLARE_DATA helloworld_module = {
STANDARD20_MODULE_STUFF,
NULL,
NULL,
NULL,
NULL,
example_directives,
register_hooks
};
The .htacces file looks like this:
RewriteEngine on
RewriteCond %{HTTP:X-CUSTOM-HEADER} 1 [NC]
RewriteRule from.html to.html
The Rewrite-Rule is never executes fine. It always show the content of
from.html.
A server-wide RewriteRule is executed in the translate_name hook.
A directory-wide RewriteRule is executed in the fixups hook.
So you'll have to place a callback on the translate_name or on the
fixups hook and make sure your callback is executed before mod_rewrite's.
You could also try to set the header using the RequestHeader directive
of the mod_headers module. Use the option "early".

As Ben said, mod_rewrite is invoked far earlier than your handler
(handlers are invoked last), since it hooks onto the translation part of
the http process. If you intend for your module to do the same, you
change your hook function accordingly:
static void register_hooks(apr_pool_t* pool){
ap_hook_translate_name(helloworld_handler, NULL, NULL, APR_HOOK_FIRST-1);
}
This will eventually be covered by the module guide in the docs (as soon
as I get some time off to write it)
With regards,
Daniel.

mod_rewrite.c does most of the interesting work in a translate_name
hook. By the time your handler hooks run, it's probably too late.
Change Request-Header before mod_rewrite
Hi all,
I just developed my first apache module following the tutorial on the apache
website. The module is responsible for adding one header value to the active
request which must be checked in a mod_rewrite ReWriteCondition.
The problem is, that this value never reaches the mod_rewrite Rule. The Header
just behaves the same as the original request. Does anyone know why? What am I
doing wrong?
My module looks like this:
static int helloworld_handler(request_rec* r){
if (!r->main) {
apr_table_setn(r->headers_in, "X-CUSTOM-HEADER", "1");
}
return DECLINED;
}
static void register_hooks(apr_pool_t* pool){
ap_hook_handler(helloworld_handler, NULL, NULL, APR_HOOK_FIRST);
}
module AP_MODULE_DECLARE_DATA helloworld_module = {
STANDARD20_MODULE_STUFF,
NULL,
NULL,
NULL,
NULL,
example_directives,
register_hooks
};
The .htacces file looks like this:
RewriteEngine on
RewriteCond %{HTTP:X-CUSTOM-HEADER} 1 [NC]
RewriteRule from.html to.html
The Rewrite-Rule is never executes fine. It always show the content of
from.html.
Thank you in advance,
Marc
