Need Help Making Destination Url Lower Case

Regex Destination url needs to be lower case.  I found this code that will convert it to lower case in the httpd.conf file.

RewriteMap lc int:tolower
RewriteRule (.*?[A-Z]+.*) ${lc:$1} [R]

Open in new window


Here is a sample url

http://www.theherbsplace.com/Garlic_Oil_Capsules_p_400.html

Open in new window

source url

https://www.theherbsplace.com/product/garlic_oil_capsules_p_400/

Open in new window

target url

I need to know if there is a better way to do this.  Because it seems very slow on Xampp.

The alternative would be to use a PHP script. To handle the case conversion and the (external) redirect.

RewriteRule (.*?[A-Z]+.*) lowercase.php?page=%{REQUEST_URI}

Open in new window

I don't recall ever using RewriteMap myself.

I found this one

<?php
if(isset($_GET['rewrite-strtolower-url'])) {
    $url = $_GET['rewrite-strtolower-url'];
    unset($_GET['rewrite-strtolower-url']);
    $params = http_build_query($_GET);
    if(strlen($params)) {
        $params = '?' . $params;
    }
    // if you don't have SSL/a security certificate at the destination change https:// to http:// below
    header('Location: https://' . $_SERVER['HTTP_HOST'] . '/' . strtolower($url) . $params, true, 301);
    exit;
}
header("HTTP/1.0 404 Not Found");
die('Unable to convert the URL to lowercase. You must supply a URL to work upon.');

but I couldn't make it work.  Do you have any suggestions?
Hi,

I found this solution working for me:

RewriteEngine On
RewriteBase /

# If there are caps, set HASCAPS to true and skip next rule
RewriteRule [A-Z] - [E=HASCAPS:TRUE,S=1]

# Skip this entire section if no uppercase letters in requested URL
RewriteRule ![A-Z] - [S=28]

# Replace single occurance of CAP with cap, then process next Rule.
RewriteRule ^([^A]*)A(.*)$ $1a$2
RewriteRule ^([^B]*)B(.*)$ $1b$2
RewriteRule ^([^C]*)C(.*)$ $1c$2
RewriteRule ^([^D]*)D(.*)$ $1d$2
RewriteRule ^([^E]*)E(.*)$ $1e$2
RewriteRule ^([^F]*)F(.*)$ $1f$2
RewriteRule ^([^G]*)G(.*)$ $1g$2
RewriteRule ^([^H]*)H(.*)$ $1h$2
RewriteRule ^([^I]*)I(.*)$ $1i$2
RewriteRule ^([^J]*)J(.*)$ $1j$2
RewriteRule ^([^K]*)K(.*)$ $1k$2
RewriteRule ^([^L]*)L(.*)$ $1l$2
RewriteRule ^([^M]*)M(.*)$ $1m$2
RewriteRule ^([^N]*)N(.*)$ $1n$2
RewriteRule ^([^O]*)O(.*)$ $1o$2
RewriteRule ^([^P]*)P(.*)$ $1p$2
RewriteRule ^([^Q]*)Q(.*)$ $1q$2
RewriteRule ^([^R]*)R(.*)$ $1r$2
RewriteRule ^([^S]*)S(.*)$ $1s$2
RewriteRule ^([^T]*)T(.*)$ $1t$2
RewriteRule ^([^U]*)U(.*)$ $1u$2
RewriteRule ^([^V]*)V(.*)$ $1v$2
RewriteRule ^([^W]*)W(.*)$ $1w$2
RewriteRule ^([^X]*)X(.*)$ $1x$2
RewriteRule ^([^Y]*)Y(.*)$ $1y$2
RewriteRule ^([^Z]*)Z(.*)$ $1z$2

# If there are any uppercase letters, restart at very first RewriteRule in file.
RewriteRule [A-Z] - [N]

RewriteCond %{ENV:HASCAPS} TRUE
RewriteRule ^/?(.*) /$1 [R=301,L]

Did you change the RewriteRule to use "rewrite-strtolower-url" instead of "page"?

Author

Commented:
yes, I did and I got it to work but it is very slow.  I tried the other script and it is 10X faster.
