Interesting “Location” header redirect

I have 2.6.1 installed and running and everything is good… Every once in a while, I have issues accessing the main page, and excluding the load-balancers, firewalls, etc., I see an odd Location header for the blog.

The blog is in the (example) location: http://www.somedomain.tld and the physical location is the root area of the webserver directory for this installation… in other words, it not in /blog, etc.

When I telnet to the webserver and issue the GET command manually, I get the following (example):

(root):xweb1> telnet 192.168.1.155 80
Trying 192.168.1.155...
Connected to 192.168.1.155.
Escape character is '^]'.

Notice the “Location:” header has the host.domain I entered appended at the end of the server name. Most of the time this is not a problem, but I want to eliminate this as an issue.

Can someone tell me why this is doing that? The web server (Apache) has the index.php as the Index file as well. As you can see, I’m running WP Super Cache as well. Here’s the .htaccess file for reference as well:

My browser just sits there like it’s hung up, waiting for a connection to time out. Very odd. No errors in the error log, like it’s in an infinate loop or something, so that why I’m thinking there’s something else going on.

Thanks in advanced for any help.
