Most Web content will be accelerated, but there are certain exceptions:

What will be accelerated?

• All text - HTML, markup, and javascript
• Streaming media, and audio and video files
• Most graphics & photos - including jpeg and gif images
• Secure pages, such as those used for online banking and credit card forms and pages accessed over VPN
• Most banner ads - including animated gif images and Macromedia Flash content Files downloaded outside your browser using FTP
• All browser-based emails
• All emails that contain images - even when read in a dedicated email program
• MP3 files, executables & other files - when downloaded from within your web browser (depending on the quality of your connection)

What stays the same.

• Secure pages, such as those used for online banking and credit card forms and pages accessed over VPN.
• Streaming media, and audio and video files --Why not compress streaming media? Propel does not compress streaming media because video files and audio files delivered in the streaming format have already been compressed to the extent possible. To attempt further compression would degrade the streaming media past an acceptable level.
• Files downloaded outside your browser using ftp.
