How to add referer header in external redirect?
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,
ajxs.

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

err_headers_out to be preserved when an errordoc is sent for non-2xx response.

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 .
Thanks,
ajxs

Try
apr_file_t *fd;
apr_file_open(&fd, "filename", APR_READ, 0, request->pool);
apr_off_t file_size = 0;
apr_file_seek(fd, APR_END, &file_size);

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().

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.
