access log and the request object
Hi, I am currently developing a Perl based apache module and was wondering if such a functionality was available. From within the module would it be possible to modify the request object so that the url that gets logged to the access.log is different from what the client actually requested? For example, if a client requested /file which was redirected to this module could it modify either the request object or some apache internal so that it gets written in the access log as /file?session=1234567890abcdef . I apologize if this is readily available from some FAQ as i have been unable to find this information. Thanks for your time.

This is untested, but I believe that mod_log_config logs, as part
of the %r CustomLog directive, r->the_request, which is the first
line of the request (i.e., "GET /file HTTP/1.0"). It might be
possible to do something like:
my @request = split / /, $r->the_request;
$request[1] = sprintf "%s?session=%s", $request[1], $r->param('session');
$r->the_request(join ' ', @request);
assuming that $r->the_request is not read-only.
Another option is to use CustomLog to log something other than
%r, like %{session}e to log an environment variable, or %q to log
the query string:
CustomLog "%h %l %u %t \"%m %U%q %H\" %>s %b"
%m is the method, %U is the requested url, %q is the query
%string (or '' if no query string), %H is the request protocol.

Re: access log and the request object
How about writing your own log handler
PerlLogHandler My::LogModule
or in your code
$r->push_handler(PerlLogHandler => \&MyLoghandler);
sub MyLoghandler{
my $r=Apache::Request;
code to log info to file
}
the push_handler method does not pass the request object to the subroutine.

Re: access log and the request object
I once used this:
Is PerlCleanupHandler the same as LogHandler?
As far as I remember putting the code in the cleanup phase would mean
logging after finishing the request cycle with no delay for the client.
Is that true?
SetHandler perl-script
PerlHandler Bankers::BedrijfswagensLijst
PerlCleanupHandler Apache::LogDBI
package Apache::LogDBI;
use Apache::Constants qw(:common);
use strict;
use DBI ();
use Apache::Util qw(ht_time);
use constant DSN=> 'dbi:mysql:koeweide';
use constant DB_TABLE => 'access_log';
use constant DB_AUTH=> ':';
sub handler {
my $orig =shift;
my $r = $orig->last;
my $date= ht_time($orig->request_time, '%Y-%m-%d %H;%M:%S'
,0);
my $host= $r->get_remote_host;
my $method = $r->method;
my $url = $orig->uri;
my $user= $r->connection->user;
my $referer = $r->header_in('Referer');
my $browser = $r->header_in('User-agent');
my $status = $orig->status;
my $bytes = $r->bytes_sent;
my $dbh = DBI->connect(DSN,split ':', DB_AUTH);
my $sth = $dbh->prepare("insert into ${\DB_TABLE} values
(?,?,?,?,?,?,?,?,?)");
$sth->execute($date,$host,$method,$url,$user,$browser,$referer,$status,$bytes);
$sth->finish;
return OK;
}
1;
