Leverage browser caching and Enable compression

[lleemon]

On PageSpeed Insights they recommend highly doing two things:

1) Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

2) Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.

We are with Network solutions and believe they are using IIS 6 with regular asp.net code. Some of the images are using Amazon S3/Cloudfront.

How do we implement the above items? Any good documentation? I see a lot for IIS 7.

Thanks.

For caching, i think modern browsers can manipulate the case better that setting it manual.Can be wrong tho.
