htaccess to webconfig

I am trying to run Candy XMPP webclient ( http://amiadogroup.github.com/candy/ ) under IIS. However, since it depends on RewriteRule in htaccess, I am unable to get it to login (I have already edited index.html to reflect the configuration on my XMPP server)

The htaccess of candy has only the following:

AddDefaultCharset UTF-8
Options +MultiViews
RewriteEngine On
RewriteRule http-bind/ http://localhost:5280/http-bind/ [P]

I am new to IIS and don't know how to convert htaccess files to web开发者_StackOverflow社区.config

There's now a guide for IIS in the official Candy wiki: https://github.com/candy-chat/candy/wiki/HTTP-Proxy-Configuration#iis
