Version 9.7 of the Hiawatha webserver has been released. With this new version, you are allowed to use the UseToolkit opion in a .hiawatha file at the root of your website. In an UrlToolkit rule, you can now check for the used request method. The default value of DHsize has been increased to 2048 and the PolarSSL library has been updated to 1.3.8. For other changes, please read the changelog.
For the next release, I will take a look at supporting websockets. Since I'm not familiar with websockets, I could use some help with that. If you are a websocket expert, please read this forum topic.
