Question

Is there an equivalent to mod_pagespeed Apache module but for IIS?

Answer 1

This isn't a direct mod_pagespeed replacement but does some work towards reducing the number of requests, minifying and bundling JS and CSS.

It even automatically provides lossless compression of PNG-images and creates sprites of your background images. See the RequestReduce library.

(not tried it myself)
