I'm writing a function to handle certain requests. I've
registered this function with Ns_RegisterRequest(). My module
loads and my function is called to process requests. So I'm doing
good so far.
But there is some information I can't get my hands on. I've
looked lots of the AOLserver C API documentation, but have not
found much about this.
I need to be able, from my registered function, to retrieve things
like the script name/path, the remote (client) address, etc.
So, is there some documentation somewhere on how to get the value
corresponding to the following CGI variables? I've put a note
next to the ones that I've figured out:
SERVER_SOFTWARE
SERVER_PROTOCOL
SERVER_NAME -- Ns_ConnServer()
SERVER_ADMIN
SERVER_ADDR
SERVER_PORT
REMOTE_ADDR
REMOTE_PORT -- Ns_ConnPort()
REMOTE_USER -- Ns_ConnAuthUser() ?
REQUEST_METHOD
REQUEST_URI -- Ns_ConnLocation() returns the base URL,
but not the whole URI.
QUERY_STRING -- Ns_ConnGetQuery()
SCRIPT_NAME
PATH_INFO
HTTP_USER_AGENT
HTTP_COOKIE
HTTPS
CONTENT_TYPE
DOCUMENT_ROOT
HTTP_ACCEPT
HTTP_REFERER
In particular, I need the SCRIPT_NAME. For example, if the
request is:
http://www.myhost.com/xxx/yyy/zzz
then I need to be able to retrieve "/xxx/yyy/zzz". And, since I
did *not* use flag NS_OP_NOINHERIT when I called
Ns_RegisterRequest(), I don't know what that is.
I did a test, and found that these are *not* available as
environment variables when my registered C function is called.
Is there a struct somewhere that contains some of these items?
I've read the C examples (at
http://aolserver.com/docs/devel/c/c-examples.html).
But, none of them seem to show any awareness of the client, the
request, etc.
I've been able to find a few, but can't find the rest. Is there a
document somewhere about this. It'd be great if there were a
document on how to convert a CGI application written in C into an
AOLserver loadable module with a registered function.
One additional question -- Many functions return a char *. Am I
correct that these return a pointer to a const char *? So I do
not need to free these, right?
Thanks for help and pointers.
