At the moment there is no such option in inets. If there is a good
enough reason I could perhaps add one, but for the moment it does not
feel very prioritized! As I see it the real problem is that your
application is not abiding to the standard.

>From the RFC 2616: HTTP header fields, which include
general-header (section 4.5), request-header (section 5.3),
response-header (section 6.2), and entity-header (section 7.1) fields,
follow the same generic format as that given in Section 3.1 of RFC 822
[9]. Each header field consists of a name followed by a colon (":")
and the field value. Field names are case-insensitive.
