Condensing RewriteConds

[keyplyr]

I wish to add this UA: "iVia-PageFetcher" to my disallow list. I already have:

RewriteCond %{HTTP_USER_AGENT} ^Page(Grabber¦Fetcher) [NC,OR]

Which is the better way to add this new UA into the existing RewriteCond.

- This (with no beginning anchor)?

RewriteCond %{HTTP_USER_AGENT} Page(Grabber¦Fetcher) [NC,OR]

- Or this (with the variable)?

RewriteCond %{HTTP_USER_AGENT} ^(iVia-)?Page(Grabber¦Fetcher) [NC,OR]

Thanks.

The safe way would be to use your second option. But since most page grabbers and fetchers are malicious anyway, if I were to ban them, I would use your first option.
