1) I have a Wordpress multisite subdomain installation with about 100 sites in the network. Network Admin - Sites (All Sites) shows them like this: main site: "www.domain-name.com" all other sites: "subdomain-name.domain-name.com" there is also a domain mapping plugin, so they all get access as separate urls: http://domain-name1.com/ http://domain-name2.com/ ... http://domain-name100.com/ 2) Currently urls on all blogs are set to: http://domain-name.com/2012/10/26/post-name http://domain-name.com/category/category-name (I used today's date as an example) This is also the way domains show in Google and Bing search results 3) I am going to remove "2012/10/26/" and "category/" from the urls, so they are gonna look like this: http://domain-name.com/post-name http://domain-name.com/category-name ...and I need to have a rewrite rule that takes care of redirecting people coming from serps to these new urls 4) I have something like this right now: RewriteRule ^([0-9]{4})/([0-9]{2})/([0-9]{2})/(.*)$ http://domain.com/$4 [L,R=301] Code (markup): RewriteCond %{HTTP_HOST} ^domain\.com RewriteRule ^([0-9]{4})/([0-9]{2})/([0-9]{2})/(.*)$ http://domain.com/$4 [L,R=301] Code (markup): but I am not sure if it is correct / if it is gonna work right, and also I need to have a rule for all 100 websites, and not just one. These versions (only one of them was meant to be used) dont include the "category/" part either. 5) If somebody would have an idea how to do that it would be great. Thank you in advance for any info.
