It may be possible to get rid of this headache, by having modified HTTP0
servers look for the blank line as a terminator *only* if the HTTP/1.0
protocol identifier is part of the GET request on the first line. The idea
is that an HTTP0 request:

GET /some/url/or/other[CRLF]

is handled as before, while an HTTP/1.0 request

GET /some/url/or/other HTTP/1.0[CRLF]
More: headers go here[CRLF]

is (properly) slurped up completely before the server starts sending back

Or am I missing something? :-|...
