Error in Apache module...

Hi,

we are trying to create an apache module which catch web requests and
does evaluation of the content_type string.

Here a snippet:

.....
char *type = ap_table_get(r->headers_in, "Content-Type");
char *posizione = strstr(type,"html");
.....

....but when we evaluate posizione....

if (posizione == NULL) return OK;

I get a blank page with header RESPONSE: HTTP/0.9 200 OK - probably
there is a runtime error. I am a newbie in Apache Modules, please let
me know where is the error.

Thanks!

Yes, "type" points to a string, but we don't understand because there
is a runtime error when we evaluate "posizione".

The runtime error give us in output a blank web page bacause this sw
is an Apache Module.


Any idea?

So during the execution of the code, you are sure that at the point
which pete marked, 'type' is really pointing to a valid string, and
not to garbage or null or something? Can you printf the string to
console or into a file or something?
'type' is not pointing to a string which contains the letters
'html',and so posizione is null?
are you actually getting an error or is this just your guess as to
what is wrong?
