This is my asp.net 2.0 solution for caching gravatar images. The gravatar service is great, but sometimes the service can get bogged down.

Features

• Will cache images as well as page requests
• Customizable timeout for gravatar.com request
• Customizable duration to use local cache before getting live icon
• Fallback if gravatar.com service is still not online but local cache exists

Requirements

• asp.net 2.0
• fulltrust web hosting

Installation

• Extract contents of gravcache.zip to a folder on your web server.
• Make sure the folder is named 'gravcache'
• Setup the folder as an asp.net 2.0 starting point
• Open gravcache.ashx
• Confirm the default configuration or make changes
• Make sure the folder you specify in private string CacheStorageFolder = "./gravcache/" has asp.net write access

Usage

• Once you install the script just replace all references of
• http://www.gravatar.com/avatar.php with http://yourhost/gravcache/gravcache.ashx
