What types of content does the Access 1 Accelerator speed up?

The Access 1 Accelerator significantly speeds up web page access. To achieve this speed up, proprietary lossless compression is applied to text, html, xml, javascript and style sheets. Proprietary image compression is applied to gif images, jpeg images and Flash content.
Access 1 also accelerates email traffic (POP3 and SMTP)using lossless compression.
Access 1 does NOT speed up file downloads (over FTP or file sharing programs), streaming audio/video and HTTPS (secure web sites).
