How do I use .htaccess conditional redirects for multiple domains?
- by John
I'm managing about 15 or so domains for a particular promotion. Each domain has specific redirects in place, as shown below. Rather than make 15 different .htaccess files that I would later have to manage separately, I'd like to use a single .htaccess file and use a symbolic link into each website's directory.
The trouble is that, I can't figure out how to make the rules apply only for a specific domain. Every time I visit www.redirectsite2.com, it sends me to www.targetsite.com/search.html?state=PA&id=75, when it should instead be sending me to www.targetsite.com/search.html?state=NJ&id=68.
How exactly do I make multiple RewriteRules apply for a given domain and only that domain? Is this even possible to do within a single .htaccess file?

# catch-all rule, using the same id as the organic visit

Thanks for any help you may be able to provide!
