setting up a rewrite map to 301 redirect old URLs to new as part of a site relaunch.. for the most part, i should be fine with some global rules (with a few link specific ones before as well)
however, the following got me stumped:
want to redirect
the basic redirect is simple, however, spaces are replaced by underscores '_' in the old URL and need to be replaced by hyphens '-' in the new URL.
is there a way to do this replacement inline, so-to-speak?
my alternative is to just define a RewriteMap txt file with: oldURL newURL pairs.
any idea what the efficiency implications are of using RewriteMaps?
