Client fd?
Hi, Anyone knows where the socket pointing to the client is stored in apache 2? In apache 1.3 it was in r->connection->client->fd Tx, Vinod. ------- Vinod Panicker <[EMAIL PROTECTED]> Sr. Software Designer Geodesic Information Systems Ltd.
Response terminator
Hi,
Can anyone pls tell me where in the apache source is the HTTP response
terminator ("\r\n\r\n") being appended to the response?
Tx,
Vinod.

RE: Client socket
I feel like kicking myself! Forgot all that I had learnt abt sockets! What I actually wanted was the ability to use the socket from another process. I obviously cant do that in this case since the socket that has been opened is local to the process (DUH!) Now I want to pass this socket to another application, which can write to it when required. I'm sitting with stevens right now, hunting for ways in which I can pass open file descriptors to another process :) Any help would be welcome. I don't require the input filters, since I want to write to the socket of a keep-alive connection later. Was just wondering if I can do it in a simple way, or I'll have to use libnet to do it Tx, Vinod. --- Vinod Panicker <[EMAIL PROTECTED]> Sr. Software Designer Geodesic Information Systems Ltd. -Original Message- From: Sander Striker [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 30, 2002 2:54 PM To: [EMAIL PROTECTED]; Vinod Panicker Subject: RE: Client socket > From: Tony Finch [mailto:[EMAIL PROTECTED]]On Behalf Of > 'Tony Finch' > Sent: 30 May 2002 11:01 > On Thu, May 30, 2002 at 11:03:05AM +0530, Vinod Panicker wrote: > > > > I need the actual socket that apache uses to communicate with the > > client in the php module.

Staying away from the socket is in general a better idea. You get all the data through the input filters, bypassing those means you lose out on a lot of functionality. Sander
RE: Client socket
Tx a million for your reply. I need the actual socket that apache uses to communicate with the client in the php module. Is it available somewhere in the request_rec structure? I've been trying to get this for ages now.

Each connection is handled in a different process and each process's fd 3 is different. If a process fork()s two children and each child accept()s a connection they will each receive a different connection but it will be allocated the same fd number in each child.

RE: Client socket
Hi Jeff,
Thanks for your reply...
Let me explain what exactly I did.
I made changes to the php_apache.c file and added a new php function of
my own, which is supposed to return the client socket when called from a
php script. Here is the code for the function -
---
/* {{{ proto int apache_client_socket()
Get the client socket */
PHP_FUNCTION(apache_client_socket)
{
RETURN_LONG(((request_rec
*)SG(server_context))->connection->client->fd);
}
---
I recompiled php and made a module out of it. Worked perfectly. Now, I
wrote a php script with the following code -
---
---
This script I call from the browser, and everytime it displays a '3'. I
even called it from different browser windows, still the same.
That cant be alright since if the fd is 3 as shown in one browser
window, it has to be something different in the other window since the
browser defaults to a keep-alive connection, and the fd's have to be
different.
I'll would tell you why I need the socket, but I've described it so many
times that I'm gonna die :( I'll forward you a mail if you are really
interested.
Tx,
Vinod.

Why is 3 incorrect? Did you do lsof on your httpd process while stopped
in the debugger to verify that 3 is (or is not) the connection to the
client?
Why do you need access to the socket?

Client socket
Hi, Where is the client socket fd stored in the request_rec structure? Is it either of the r->connection->client->fd or the r->connection->client->fd_in variables? I tried accessing the values, but both the variables show the value '3' for every request passed to the php module.
