If you were going to store a user agent in a database, how large would you accomdate for?
I found this technet article which recommends keeping UA under 200. It doesn't look like this is defined in the HTTP specification at least not that I found. My UA is already 149 characters, and it seems like each version of .net will be adding to it.
I know I can parse the string out and break it down but I'd rather not.
EDIT
Based on this Blog IE9 will be changing to send the short UA string. This is a good change.
