Appendix C. Checked MIME filetypes
The HTTP Application Layer Gateway has the ability to verify that the contents of a file
downloaded via the HTTP protocol is the type that the filetype in its filename indicates.
This appendix lists the MIME filetypes that can be checked by NetDefendOS to make sure that the
content matches the filetype of a download. Checking is done if the Check MIME Type option is
enabled as described in Section 6.2.2, “HTTP”. Checking also always done if the filetype is ticked
in the Allow Selected list for an HTTP ALG.
