Setting custom expiry time for different paths

Thanks @Philip_Clarke for the quick confirmation. Is this something boost module might have as a feature in the future? If not, I was thinking of writing a small addon utility module to work with boost.

I have created a module that allows users to set custom rules to change the cache lifetime of different pages cached by boost. The module is available at

http://drupal.org/project/boost_custom_expire_rules

Currently supported rules are

• Node age based cache expire rule
  This would allow for older nodes to have an longer cache lifetime. For example setting a cache lifetime of 1 week for nodes older than 1 month and setting a cache lifetime of 1 hour for nodes fresher than 1 week.
• Node type based cache expire rule
  Different content types can be configured to have different cache lifetimes. For example setting a cache lifetime of 1 week for page nodes and setting a cache lifetime of 1 hour for story nodes.
• Drupal path / URL based cache expire rule
  This would allow for faster changing URLs like the home page or taxonomy listing pages to have shorter cache lifetimes while slower changing URLs could continue to have longer cache lifetimes.

The rules are created using a simple API that developers can use to add additional rules.
