repoze.squeeze 0.4

WSGI middleware for statistical HTML browser resource squeezing.

This package provides a WSGI middleware component which “squeezes” HTML documents by merging browser resources (javascript and stylesheets).

It uses statistical analysis to determine the optimal bundles based on the HTML documents that pass through it. Vary-headers are observed, as are resource expiration dates.

Documents that are not squeezed are given the ‘no-cache’ pragma in an expectation that we will be able to squeeze it after sufficient burn-in. Squeezed documents are served with expiration dates no later than the expiration dates of the squeezed resources which it references.

Usage

The middleware requires two following options to be set:

@cache_dir: Relative path to a directory where we store squeezed resources

@url_prefix: Path segment or full base URL that will be used to serve the cache directory as static files.

Remember to configure a WSGI application to serve the squeezed resources!
