Hi Erunafailaro,
It does make sense to use it in combination with HTTP Express. WP Super Cache creates a cache copy for the document users see.
HTTP Express instead optimizes browsers’ cache use by adding right headers to images, css, swf and javascript (which are not processed by WP Super Cache as I can see from a quick overview)
Hi Milber,
we have tested wp-private-access on a 2.9.1 installation and all works correctly.
May you post your hosting details to help us reproduce the enviroment in which you are encountering the problem.
