Hi,
Anyone had similar issue installing Mozilla extension over S360? Access policy allow all sort of object (non of the Block Object type box is checked). When I look at http header, it shows:
Content-Type: application/x-xpinstall
which should match Mozilla/Firefox Extension but instead policy trace show it is blocked due to custom MIME type settings (using url below):
URL used:
http://releases.mozilla.org/pub/mozilla.org/addons/1843/firebug-1.4.3-fx.xpi
URL Check
URL Category: Computing & Internet
WBRS Score: 6.9
Object Size: 690894 bytes
Policy Match
Decryption policy: None
Routing policy: Global Routing Policy
Identity policy: AD_AUTH
Access policy: GeneralGroup
Final Result
Request blocked
Details: Request blocked based on custom MIME type settings
Trace session complete
Could it be S360 detect .xpi file as custom type?

Check your GeneralGroup access policy under the column objects for any "Block Custom MIME Types" custom settings.
The accesslogs should also help as well to show exactly what it was actually blocking.
Use the grep command:
Using the grep command from the CLI, you can view a specific request from specific clients to troubleshoot why it was allowed, blocked, or which group it matched on.
Paste the response from the CLI and we can assist in analyzing the access logs.
1. Log into the CLI.
2. Type in "grep".
3. Select the accesslogs.
4. Type in specific client's ip address for the regular expression
5. Type in "Y" for do you want to tail the accesslogs.

Thanks khoa,
I figure global policy actually blocking Mozilla/extension. It work once I allow that.

Sorry to ask another question, how do we create a new custom MIME-Type?
Under Objects -> Executable Code, I could only see
a) ActiveX Plugin
b) Windows Executable
c) Java Program
d) Unix Executable
e) Mozilla/Firefox Extension
The file I am trying to download is http://download.tomtom.com/sweet/application/releases/v2_7_2_1825_win.exe which is blocked as "application/x-dosexec". How can I create another custom Executable Code to I can allow this file to download?

Oh, another question. Why would Ironport label MIME-Type as application/x-dosexec while my Mozilla HTTP Header detect it as Content-Type: application/octet-stream.
Appreciate your help.

If you want to allow "windows executable" you will need to uncheck the box matching your desired access policy. "windows executable" covers several mime types:
application/x-msdos-program
application/x-msdownload
application/x-dosexec
Not sure why Mozilla detects the content type as such, unless it was not the actual object in question or it was what was seen in the custom http headers and not a file detection log.
