Additional Resources

Browsercaps For ASP.NET

Many people ask me where they can find a regularly updated, accurate browsercaps insert for ASP.NET. I tell them my friend Owen provides just such a file and it can be downloaded from his site.

Bot Blocker Resources

My friend Owen also hosts a great list of bot blocker resources.

User Agents for Programming Libraries and Command Line Tools

My friend Bill and others maintain this list of default user agents for programming libraries and command line tools, along with an explanation of what each one does.

Discuss Search Engine Bots and User Agents

WebmasterWorld is the premiere website for intelligent discussions amongst internet professionals. I have been a member since approximately 2000. Most of my time there is spent in the Search Engine Spider and User Agent Identification forum. Join me there and stay abreast of the latest goings on with bots and other user agents.

PHP Scripts

If you are in a shared hosting situation where the host doesn't keep browscap.ini updated, or worse don't even provide access to it, or you just can't stand the bugginess of PHP's get_browser() function, then these links are for you. They each implement their own browscap.ini parser and let you set the path to the file. And they each automatically check for and download my updated files. I highly recommend the first link to Jonathan Stoppani's PHP Browscap class:

Optimized For PHP5
Optimized for PHP and Linux
