301 partial URL match

apache mod_rewrite partial match 301

[elHelgo]

When I used to use blogger, it created static html files that Google still hits today. Something like the following:

sitename.com/blogarchive/2005_06_01_sitename_archive.html

A few years ago, I started coding everything up myself, but noticed that I need to 301 these. There are around 40-50 of them, so I don't want to go in one by one and do it. Does anyone know a way to do a mod_rewrite rule on just a partial part of the link above?

Here's the new part to where they should be going:

sitename.com/date/[year]/[month]/

I only care about stripping out the year and month and I don't care about anything after the "2005_06" in the example above.

Any help would be appreciated.

Thanks.

Yes, likely a one line RewriteRule with simple pattern matching to grab the year and month into backreferences to use in the substitution URL.

What code have you tried so far?

I've tried this, but to no avail:

RewriteRule /blogarchive/([0-9]+)_([0-9]+)_$ sitename.com/date/$1/$2/ [R=301,L]

Including the $ means the requested URL "must" end in an underscore.

The requested URL actually has more characters (which you want to ignore) after the underscore.

Simply remove the $ to let that happen.

Additionally, if this code goes in your .htaccess file, replace the leading / of the pattern with a ^ instead.

Thanks, that did the trick.
