int a_Misc_content_type_check | ( | const char * | EntryType, |
const char * | DetectedType | ||
) |
Check the server-supplied 'Content-Type' against our detected type.
(some servers seem to default to "text/plain").
There are many MIME types Dillo doesn't know, they're handled as "application/octet-stream" (as the SPEC says).
A mismatch happens when receiving a binary stream as "text/plain" or "text/html", or an image that's not an image of its kind.
Note: this is a basic security procedure.

int a_Misc_get_content_type_from_data | ( | void * | Data, |
size_t | Size, | ||
const char ** | PT | ||
) |
Detects 'Content-Type' from a data stream sample.
It uses the magic(5) logic from file(1). Currently, it only checks the few mime types that Dillo supports.
'Data' is a pointer to the first bytes of the raw data.
Return value: (0 on success, 1 on doubt, 2 on lack of data).
