MIME Sniffing

Multipurpose Internet Mail Extension (MIME) sniffing, the process of inspecting byte stream content to try to determine the file format of the data within it, is disabled by default in Siebel.

Since it is essential for the browser to render customer files according to the Content-Type, customers are typically requested to convert their customer file content to match the Content-Type. You can enable MIME sniffing by commenting out the HttpHeaderSecurityFilter filter and its filter mapping from the web.xml file stored here:

$<Tomcat Container Location>\conf\web.xml

It is recommended that you do not enable MIME sniffing in production environments.
