With the Mime-Type application/powerpoint or application/vnd.ms-powerpoint all Powerpoint-Files will be blocked.<BR />How can i do this ? Is there any way to define a file-extension to be blocked ?<BR /><BR />Regards<BR />Jens</P> Mon, 09 Feb 2009 20:26:27 GMT https://community.cisco.com/t5/web-security/allow-ppt-but-block-pps/m-p/1170494#M539 jpuder 2009-02-09T20:26:27Z Re: Allow *.ppt but block *.pps https://community.cisco.com/t5/web-security/allow-ppt-but-block-pps/m-p/1170495#M540 <HTML><HEAD></HEAD><BODY><P>Jens,<BR /><BR />The only way to block a file extension is to use a custom category and define a regex value. <BR /><BR />For your example, you could use:<BR /><BR />\.ppt$<BR /><BR />...to allow ppt files. Custom URL categories take prescedence over file type blocking.</P></BODY></HTML> Wed, 11 Feb 2009 01:06:54 GMT https://community.cisco.com/t5/web-security/allow-ppt-but-block-pps/m-p/1170495#M540 jowolfer 2009-02-11T01:06:54Z Re: Allow *.ppt but block *.pps https://community.cisco.com/t5/web-security/allow-ppt-but-block-pps/m-p/1170496#M541 <HTML><HEAD></HEAD><BODY><P>Thank You, Josh !</P></BODY></HTML> Wed, 11 Feb 2009 05:37:55 GMT https://community.cisco.com/t5/web-security/allow-ppt-but-block-pps/m-p/1170496#M541 jpuder 2009-02-11T05:37:55Z
