User Agents    aka    http_user_agent

This page exists for the sole purpose of helping to identify the values found in so many of the HTTP_USER_AGENT cgi variables. I started this just for my own information but as so many of my projects do, it grew into something that is hopefully useful to others.

The informatin in the HTTP_USER_AGENT variable is supose to offer some usable information to your web server in identifying the client that is requesting information. Unfortunatly, most of the time this information is really of no value without looking for some specific key items encoded in the variable content.

This problem comes from the fact there is no hard and fast rules about how the contents of the variable are to be formatted. Sure, there are common items in many of the values, but more times than not there is a lot of extra junk that simply acts to confuse us. It is really ment to be picked apart when looking for specific values.

Here is what I have come up with to help you out. Simply copy and paste (or key in) a user agent string into the box below. The string will be compaired against our data and some information will be provided back. In the event you enter something we know nothing about, we will keep your entry and try to locate some information about it in the near future.
