Hi, In the converted AuthCookie (AuthCookieURL?) that also handles sessions by URL, I need a way to add the session back on the URL when Apache generates a redirect to someplace within the site (e.g. when a request is for a directory). Currently, I'm registering a 301 and 302 ErrorDocument to prefix the Location: header with the session ID. I don't like this method as it requires the ErrorDocument and prevents other ErrorDocument handlers, and adds ugly configuration in httpd.conf. And it won't work in CGI scripts that just print a Location: header. Is there a mod_perl solution to this problem without using an ErrorDocument? Could I override $r->send_http_header or would that not work with internal Apache redirects? Shooting in the dark, I tried to tie *STDOUT in a fixup handler, but the PRINT method never gets called. But this isn't really a pipelined handler operation -- perhaps mod_perl ties *STDOUT after the fixup handler? It would be nice in mod_perl to be able to filter everything that's going to the client -- even non-mod_perl generated responses in ways other than using pipelined PerlHandlers. Anyway, I'm searching for suggestions as at this point I'm just guessing... Thanks, Bill Moseley mailto:[EMAIL PROTECTED]
