mod_rewrite with prg rewritemap

[alinux]

Hi
I got a mod_rewrite condition that relies on the output of a perl script, the perl script runs fine from command line, however when I try apache the condition is not matched.
Any help ?
Thanks


########.htaccess file

rewriteengine on
RewriteCond ${dash2score:%{REMOTE_ADDR}} yes
RewriteRule !^index.php$ http://www.howstuffworks.com [P,L]


#########apache2.conf
RewriteMap dash2score prg:/var/www/getIpStat.pl


#########getIpStat.pl
#!/usr/bin/perl
use DBI;
# Connect
my $dbh = DBI->connect('DBI:mysql:announcments:localhost','root', 'xxxxxxxx')
or die "Could not connect: $DBI::errstr\n";
# Get post_name
my $post_name = <STDIN>;
# my $post_name = $ARGV[$0];
chomp($post_name);
# Get data from db
my ($ID) = $dbh->selectrow_array("SELECT state FROM ips WHERE ip = ?", undef, $post_name);
# Display Results
print $ID;

Is "yes" returned by the script?
What is returned when there is no match?

Edit:

You only needed one thread.

Hi

.htaccess I got

Code: Select all

RewriteEngine on
RewriteCond ${dash2score:%{REMOTE_ADDR}} =yes
RewriteCond %{REQUEST_URI} !/index\.php$
RewriteRule ^(.*)$ http://www.howstuffworks.com/$1 [P,L]

Script is :

Code: Select all

#!/usr/bin/perl

while (my $post_name = <STDIN>) {
print "yes";
}

Log is :

Code: Select all

Well since the script does echo yes on any input it should match right ?

(4) [perdir /var/www/] RewriteCond: input='' pattern='=yes' => not-matched

Nothing is returned by your script.

The documentation says

# A common mistake is to use buffered I/O on stdout. Avoid this, as it will cause a deadloop! ``$|=1'' is used above, to prevent this.

It also has an example script.

Hi Thanks for the hint, for testing / debugging purposes I change the script to:

#!/usr/bin/perl
$| = 1;
while (<STDIN>) {
# ...put here any transformations or lookups...
print $_;
}

In other words i simply returns whatever you throw at it.

And I change .htaccess to:

RewriteEngine on
RewriteCond ${dash2score:yes} yes
RewriteCond %{REQUEST_URI} !/index\.php$
RewriteRule ^(.*)$ http://www.howstuffworks.com/$1 [P,L]

So now, the dash2score perl script gets yes as an argument and it returns yes, i tested it from cmd line.

However, once I test it in apache all I get is:

192.168.0.189 - - [30/Jun/2009:16:19:26 +0300] [192.168.0.1/sid#89eaba8][rid#8be28e0/initial] (5) map lookup FAILED: map=dash2score key=yes
192.168.0.189 - - [30/Jun/2009:16:19:26 +0300] [192.168.0.1/sid#89eaba8][rid#8be28e0/initial] (4) [perdir /var/www/] RewriteCond: input='' pattern='yes' => not-matched

When you run it from the command line, does it wait for you to enter something, then output what you entered and then wait for more input?

Try adding a newline to the end of the print statement.

Hi
WHen run from cmd line it keeps waiting for input it does not terminate I did try with a new line in the script

print "\n";

It does show in cmd line that a new line is added..but from within apache the same problem exists.

THanks

Then i don't know what's wrong. You could try a RewriteMap written in a different language (to see if it works).
