Looking at this further, the header value is defined as TEXT. TEXT is
defined as OCTETs that are not control characters. An OCTET is an 8 bit
character. As far as I can see it should be up to the entity putting
data into the header to make sure it does not contain control
characters. In your case, base64 would thus be safe.
What do you think about my proposal to add the "E" option with the described
behavior to the Header and RequestHeader directive?
Keeping in mind that HTTP 1.0 still warns:
However, folding of header lines is not expected by some
applications, and should not be generated by HTTP/1.0 applications.
HTTP 1.0 is obsolete - Apache follows HTTP/1.1, defined in RFC2616.
