@import rules of any complexity is calculated. Also inline code is parsed and merged, this can significantly decrease HTML pages’ size.
Powerful mix of WEBO Site SpeedUp performance options allows you to easily manage balance between performance and cache integrity. Here you can choose either to check files’ modification time or not, or just disable check for cache integrity – this completely eliminates HDD requests while page load and greatly improve performance, and much more.
WEBO Site SpeedUp incorporates a large number of gzip techniques. They include
ob_gzhandler usage, static gzip (to prevent CPU wasting) and optional gzip check via cookies (to defeat firewalls). Also the product supports all font types and has advanced support for old and tricky browsers. Minify rate here is up to 88%.
WEBO Site SpeedUp has a large predefined set of rules to tune Apache usage for your website. These rules include
mod_filter for gzip,
mod_rewrite for static gzip,
mod_rewrite for client side caching, and
mod_setenvif for improved backward compatibility.
By default all static files are cached for 10 years. To force cache reload either GET parameter, or new file name (what provides complete proxy caching support) is used. Additionally you can set client side caching for HTML files and their conditional (ETag) caching.
CSS Sptires technology is completely cross browser and allows you to significantly reduce number of CSS images on your website.

mhtml approach. In this case all CSS images are included to resource file and are loaded all together.
.svg files are excluded. Also there is optional CSS files separation and ability to load resource file on
