Some cOS Core Application Layer Gateways (ALGs) have the optional ability to verify that the contents of a downloaded file matches the type that the filetype in the filename indicates. The filetypes for which MIME verification can be done are listed in this appendix and the ALGs to which this applies are:
The ALGs listed above also offer the option to explicitly allow or block certain filetypes as downloads from a list of types. That list is the same one found in this appendix.
For a more detailed description of MIME verification and the filetype block/allow feature, see Section 6.1.2, HTTP ALG.
