I was checking out a post at Tachyon City, a post with some great pictures of hand-carved pumpkins. I liked it and thought I’d leave a comment and then got the following message, a message I’ve never seen before as a response from a WordPress blog.
“Your comment was rejected as your browser’s user agent has changed since you viewed the post.”
Honestly, I have no idea what that means. Maybe a coder or techie out there could enlighten me.

Huh. Weird. Are you writing from behind a proxy or anything like it?

A typical strategy in maintaining identity information about visitors to web pages is to use some unique information about their visit when they first arrive, arrange it just so, and then encrypt it into a string of consecutive characters, in this case evidently called a user string (that your browser generates). The server–or a program layer–that verifies the user string as you move in the domain where the page resides, must have detected a change in your identifying information, which could be any bit of the information unique to your first arrival.
