Today I needed to rewrite a list of about 1000 URL’s to a new location. Our product database was cleaned and new URL’s were created… Using RewriteMap from Apache’s Mod_rewrite comes in handy here.<\/p>\n

In my case I needed to rewrite URL’s like this:<\/p>\n

www.exampledomain.com\/en\/product1234\/product_detail.php<\/p>\n

to<\/p>\n

www.exampledomain.com\/en\/travelbox_12\/product_detail.php<\/p>\n

Where in my URL’s I had a 1000 different ‘poducts1234’ to rewrite to a new URL.<\/p>\n

 <\/p>\n

Here’s the HOWTO:<\/p>\n

Create a textfile on your server with 2 columns. Something that would look like this:<\/p>\n

product1234 travelbox_34\r\nproduct1235 travelbox_13\r\nproduct2310 case_07\r\nproduct3126 case_12\r\nproduct9320 anotheritem_54\r\n....\r\n....\r\n<\/pre>\n
And save it to a folder you wish, eg<\/p>\n
vim \/etc\/apache2\/conf.d\/productrewrites.txt<\/pre>\n
from this file, \u00a0create a rewrite database, \u00a0more info: httxt2dbm<\/a><\/p>\n
httxt2dbm -f db -i \/etc\/apache2\/conf.d\/productrewrites.txt -o \/etc\/apache2\/conf.d\/productrewrites.db<\/pre>\n
Once done, \u00a0open your vhosts config and add the following configuration:<\/p>\n
RewriteEngine On\r\nRewriteMap rewrites dbm=db:\/etc\/apache2\/conf.d\/productrewrites.db \r\nRewriteCond ${rewrites:$1} !=\"\"\r\nRewriteRule ^\/(.*)\/(.*)\/(.*)$ http:\/\/www.exampledomain.com\/(.*)\/${rewrites:$1}\/$2? [R=permanent,L] \r\n\r\n<\/pre>\n
A bit of clarification:<\/p>\n
The line with content:<\/p>\n
RewriteCond ${rewrites:$1} !=\"\"<\/pre>\n
creates a condition that if the rewritemap contains the URI and the value is not “” (so an empty string) then it should perform the RewriteRule<\/code>.<\/p>\n
The rewrite rule itself is pretty obvious. It’ll rewrite the URL’s for which the rewritemap is found to the new product URL, and also keep the trailing parameters.<\/p>\n","protected":false},"excerpt":{"rendered":"
