Hi all, under Apache 1.3 with mod_perl, I dynamically set the header calling

...
$r->headers_out("Content-Disposition",$my_value);
return OK
...
[download]

It works. The header name is sent in lowercased form ('content-disposition'), which is correct considering HTTP spec. But I suspect end-user's Symbian 3rd edition that it ignores this lowercased version - it downloads the content and saves it somewhere, but it does not start installation.

Is it possible to set the header name without lowercasing?
