Is this var/symbol exstied in newlisp?
I found this code in dragonfly framework,but I googled this, found nothing match it.
//http://code.google.com/p/dragonfly-newlisp/source/browse/example-site/dragonfly-framework/lib/request.lsp?r=26dd4d9a55a69ad235653ab0e1da3e59d95e46d6
(if (and (setf temp HTTP_CONTENT_TRANSFER_ENCODING) (= temp "binary"))
(handle-binary-data)
(and (setf temp CONTENT_TYPE) (starts-with temp "multipart/form-data"))
(handle-multipart-data)
(and (read (device) temp MAX_POST_LENGTH) temp)
(dolist (pair (parse-query temp))
(add-keyvalue-to-ctx (first pair) (last pair) $POST)
)
)
What is this HTTP_CONTENT_TRANSFER_ENCODING for?
HTT_CONTENT_TRANSFER_ENCODING is environment variable, created from the Content-Transfer-Encoding (//http) request header.
You can continue searching for Content-Transfer-Encoding, but in short, it tells how incoming data are encoded.
thanks
I just want to know , it this created by newlisp or else?
I can not find this HTTP_CONTENT_TRANSFER_ENCODING in newlisp codes
But dragonfly used it
So I wonder where it come from?
Ah, it's set by the web server. Here's what CGI 1.1 specification says about HTTP_* environment variables:
HTTP_*
These variables are specific to requests made with HTTP.
Interpretation of these variables may depend on the value of
SERVER_PROTOCOL.
Environment variables with names beginning with "HTTP_" contain
header data read from the client, if the protocol used was HTTP.
The HTTP header name is converted to upper case, has all
occurrences of "-" replaced with "_" and has "HTTP_" prepended to
give the environment variable name. The header data may be
presented as sent by the client, or may be rewritten in ways which
do not change its semantics. If multiple headers with the same
field-name are received then they must be rewritten as a single
header having the same semantics. Similarly, a header that is
received on more than one line must be merged onto a single line.
The server must, if necessary, change the representation of the
data (for example, the character set) to be appropriate for a CGI
environment variable.
The server is not required to create environment variables for all
the headers that it receives. In particular, it may remove any
headers carrying authentication information, such as
"Authorization"; it may remove headers whose value is available to
the script via other variables, such as "Content-Length" and
"Content-Type".
