Answers.Text: Yes, this is what I've done as well, but seems to work ok. I've set the uid so my cdv code looks like this
  
  `id,"oldUrl","newUrl",method,"dateCreated","dateUpdated","uid"
  {% set redirects = craft.entries.order('title').limit(1000) %}
  {% for entry in redirects %}{% if entry.urllegacy|length %}{{loop.index}},"{{ entry.urllegacy }}","/{{ entry.uri }}","301","2014-07-24 15:00:00","2014-07-24 15:00:01","{{ entry.id }}"

  (Asked by: username_0 on 2014-07-02)
  
  The [Reroute plugin](https://github.com/davist11/craft-reroute) is great for a handful of 301 redirects, but we have hundreds of entries and each entry has a legacy URL. Dumping this into a template as normal works fine, but thinking about if it could work with the .htaccess file directly. Has anyone tried, or would be a dangerous path?
  
  Thinking along the lines of NSM htaccess for EE.

  The more redirects you have, the better off you’re going to be having them managed *outside* of your .htaccess file, and in a database table.
  
  Each redirect in your .htaccess file comes with a slight performance hit, since mod\_rewrite needs to parse and evaluate each one individually, for every single request.
  
  If you have them managed in an indexed database table, the performance hit will be trivial – just the time it takes to make a very simple DB query.
  
  I haven’t used [Reroute](https://github.com/davist11/craft-reroute), but it looks like that’s just storing redirects in a DB table, so it’s probably going to be your best bet for managing hundreds of redirects. (Not sure how scalable the UI is, though.)
