POW: Excuse me sir, you seem to have a server in your client
Written by on February 9th, 2007 in Ajax News.
Ready to take your mind for a spin? David Kellog has created POW the Plain Old Webserver.
POW is a Firefox plugin that implements a full web server. That means that your browser client now has a server in it.
That just sounds goofy no? It can be useful though. dojo.storage needs a server to do an autoproxy with to do local storage. You could do that all via the extension.
The Plain Old Webserver uses Server-side Javascript (SJS) to run a server inside your browser. Use it to distribute files from your browser. It supports Server-side JS, GET, POST, uploads, Cookies, SQLite and AJAX. It has security features to password-protect your site. Users have created a wiki, chat room and search engine using SJS.
This version includes:
- Documentation to show you how to build a Server-side Javascript program.
- File uploading code
- SQLite interface for easy saving of persistent data
POW has more WOW than Vista!
