Re: hellp improve efficiency
Hi,
You can use the following it will reduce the amount of :
...
while () {
$uri = (split)[0];
$uri =~ s#www\.example\.com/(v\d?|so)#$1.example.com# or
$uri =~ s#www\.example\.com/admin/\?.*#www.example.com/admin/# or
$uri =~ s#www\.example\.com/([wulp])(\d+)/#$2.$1.example.com# or
$uri =~ s#www\.example\.com/([wulp])/#$1.example.com/#;
print $uri;
}
Best regards

Subject: hellp improve efficiency
Hello members,
I wrote a perl script for url redirect,shown as below,
$|=1;
my $uri = '';
while () {
$uri = (split)[0];
if ($uri =~ /\.html?\?/ or $uri =~ /\.js\?/ or $uri =~ /\.css\?/ or
$uri =~ /\.jpg\?/ or $uri =~ /\.gif\?/ or $uri =~ /\.swf\?/) {
$uri =~ s/\?.*$//;
}
if ($uri =~ m|www\.example\.com/v/|o) {
$uri =~ s|www\.example\.com/v/|v.example.com/|;
}elsif ($uri =~ m|www\.example\.com/v2/|o) {
$uri =~ s|www\.example\.com/v2/|v2.example.com/|;
}elsif ($uri =~ m|www\.example\.com/v3/|o) {
$uri =~ s|www\.example\.com/v3/|v3.example.com/|;
}elsif ($uri =~ m|www\.example\.com/so/|o) {
$uri =~ s|www\.example\.com/so/|so.example.com/|;
}elsif ($uri =~ m|www\.example\.com/admin/\?.*|o) {
$uri =~ s|www\.example\.com/admin/\?.*|www.example.com/admin/|;
}elsif ($uri =~ m|www\.example\.com/w\?v=|o) {
$uri =~ s|www\.example\.com/w\?v=|v2.example.com/v_|;
}elsif ($uri =~ m|www\.example\.com/([wulp])(\d+)/|o) {
$uri =~ s|www\.example\.com/([wulp])(\d+)/|$2.$1.example.com/|;
}elsif ($uri =~ m|www\.example\.com/([wulp])/|o) {
$uri =~ s|www\.example\.com/([wulp])/|$1.example.com/|;
}
} continue {
print $uri\n;
}
__END__
As you see,for each regex match,I've tested it twice.
Maybe it's going with low-efficiency.How can improve it?Thanks.

The /o modifier isn't desirable there. Also, because a s/// will only
replace if the match part succeeds, you can skip the test:
$uri =~ s#www\.example\.com/v2/#v2.example.com/#;
If it matters to you whether the pattern matched or not, you may test
the result in a scalar context:
} elsif ($uri =~ s#www\.example\.com/v2/#v2.example.com/#) {
# substitution succeeded, do nothing further
} elsif (...) {
Hope this helps!

Re: hellp improve efficiency
Perhaps I'm misunderstanding what you're ultimately trying to
accomplish. However, if you're doing what I think you're doing and
you're using Apache, look into mod_rewrite:

However, if you're doing what I think you're doing and you're using Apache, look into mod_rewrite: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html From my knowledge,he/she was doing nothing about Apache,but wrote a redirector for Squid cache. Also Tom,maybe using or instead of elsif is more clear,:) $uri =~ s#www\.example\.com/v2/#v2.example.com/# or $uri =~ s#www\.example\.com/v3/#v3.example.com/# or -- Chinese Practical Mod_perl book online http://home.arcor.de/jeffpang/mod_perl/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
