Long story short, I have 2 sites.

1 site sets a cookie on your machine when you have logged in.

The other site is a wordpress blog. In the index.php (at the root level), I wanted to basically shield the site from running if this cookie is not found on their machine. If it is, the blog will run like normal.

Is there a way I can do this without doing a bunch of redirects or form postings?

Thanks,
Bryan
