Allow *.ppt but block *.pps

[jpuder]

Hello,

i will allow MS Powerpoint *.ppt files but will block *.pps files. With the Mime-Type application/powerpoint or application/vnd.ms-powerpoint all Powerpoint-Files will be blocked.
How can i do this ? Is there any way to define a file-extension to be blocked ?

Regards
Jens

Jens,

The only way to block a file extension is to use a custom category and define a regex value.

For your example, you could use:

\.ppt$

...to allow ppt files. Custom URL categories take prescedence over file type blocking.
