Hook end of connection
Hi,
I need to write a module, which does something at the beginning and at
the end of each connection. I found a hook to handle beginning of
connection -
ap_run_pre_connection. It's executed quite early, which works for me.
And I need to execute some actions prior or just after connection will
be closed. I looked a lot (reviewed whole connection processing - mpm,
server\connection, http module), but wasn't able to find appropriate
hook for that.
I would appreciate, if you know a method to handle that.
BTW. On note. Hooking end of request doesn't help me, because connection
could be in keepalive state, so additional requests will be served in
the same connection.
Regards,
Victor Ronin

Won't make any difference to someone trying to set a request header in a response.

Not sure what you mean. If it's a single static image, convert it to a
C byte array and send it with ap_rwrite().

I don't know why the cookie is not sent.
Try apr_table_set(r->err_headers_out, ...);
Also, are you sure that the pointer to cookie_contents is still valid
at the very end of the request processing, that is _after_ you return
from the handler. If not, try apr_table_set instead of apr_table_setn.

Hi Sorin Manolache,
According your ways(ap_send_fd()),it is work.The picture is returned to client.But myself-set cookie content are not returned , why??
Begin sending jpg-file,I set a cookie in headers_out :
r->content_type="image/jpeg";
apr_table_setn(r->headers_out,"Set-Cookie",cookie-contence);
ap_send_fd(fd, request, 0, file_size, &bytes_sent);
return OK;
Besides,the request address of the jpeg picture ishttp://www.whut.com/portal/logout.jpg. This request is sent from the response page of ahttp://www.jjsonicIDP.com/saml/logout.action request .

Re: How to add referer header in external redirect?
Posted by Ray Morris <su...@bettercgi.com>.
It's up to the browser what to send back after being redirected.
You could either a) not send a redirect header, but rather do an
internal redirect, or b) probably better would be to append the
encoded referer to the query string.

How to add referer header in external redirect?
Posted by Whut Jia <wh...@163.com>.
Hi all,
I need some help with a redirecting/referrer issue. If I do a 303 redirect in my module (by this way below:
apr_table_setn(r->headers_out,"Location","http://idp/login.html");
return HTTP_SEE_OTHER;)
In order to I can see the referrer header when jumping to the new page,how do I solve this??
Thanks,

Do you mean ap_hook_log_transaction?
I believe it's executed at the end of request vs. end of connection.

This won't work for me (child usually serves many connection).
>Register a cleanup on the connection pool.
Got it. This will work.
Connection uses context pool and I thought initially, that it will be
cleaned only when some subsequent connection will be made. However,
I double check it now and It will be cleaned immediately when worker
will start waiting on next established connection.

Victor
