How does it work?
Utilising ZLIB and BZIP2 technology IISxpress is capable of compression ratios up to 10:1 on typical web content while retaining full HTTP standard and client browser compatibility.
IISxpress includes powerful configuration and analysis tools to allow you to customise and fine-tune your compression settings for maximum performance.
IISxpress knows what file types compress well (e.g. HTML, CSS, XML, etc.) and which file types do not (e.g. ZIP, JPG, GIF, etc.) reducing the CPU overhead by only compressing content where it will get significant gains.
