reading cookies from mod_perl HTTP request handlers

[Vishal Verma <vi...@epunjabis.com>]

Hi,

I'm unable to access/read cookies from incoming HTTP requests using
mod_perl HTTP request handlers.Here's what my relevant apache config
section looks like

<Location />
        PerlHeaderParserHandler MyModule::header_parse_handler
</Location>


My browser already has a cookie named 'foo' with value 'bar' with path &
expire times set appropriately. Here's what my browser GET request looks
like


GET /cgi-bin/login HTTP/1.1
Host: xxxxxx
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1)
Gecko/20021130
Accept:
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1
Accept-Language: en-us, en;q=0.50
Accept-Encoding: gzip, deflate, compress;q=0.9
Accept-Charset: ISO-8859-1, utf-8;q=0.66, *;q=0.66
Keep-Alive: 300
Connection: keep-alive
Cookie: foo=bar

The last line confirms that the browser is sending the cookie.

But, I'm not able to see that cookie when I print $ENV{'HTTP_COOKIE'}
within in header_parse_handler. mod_perl docs say that that you can
examine request headers in the PerlHeaderParserHandler. Am I missing
something? Am I using a wrong handler? Please help.

thanks

%ENV is setup during the fixup phase, so it hasn't been populated yet.

yes, using something like $r->headers_in.  you're actually better off using 
Apache::Cookie, which is in the libapreq distribution on cpan.

if you want to force %ENV to be setup earlier, try calling

$r->subprocess_env;

in a void context before checking %ENV - it used to segfault for me, but the 
docs says it should work.
