Return an input port containing the data at URI, and the expected number of bytes available or #f. If TEXT? is true, the data at URI is considered to be textual. Follow any HTTP redirection. When BUFFERED? is #f, return an unbuffered port, suitable for use in `filtered-port'. HEADERS is an alist of extra HTTP headers.

When KEEP-ALIVE? is true, the connection is marked as 'keep-alive' and PORT is not closed upon completion.

When VERIFY-CERTIFICATE? is true, verify HTTPS server certificates.

TIMEOUT specifies the timeout in seconds for connection establishment; when TIMEOUT is #f, connection establishment never times out.

Write information about redirects to LOG-PORT.

Raise an '&http-get-error' condition if downloading fails.

Send all of REQUESTS to the server at BASE-URI. Call PROC for each response, passing it the request object, the response, a port from which to read the response body, and the previous result, starting with SEED, à la 'fold'. Return the final result.

When PORT is specified, use it as the initial connection on which HTTP requests are sent; otherwise call OPEN-CONNECTION to open a new connection for a URI. When KEEP-ALIVE? is false, close the connection port before returning.

Return the translation of the package description or synopsis MSGID.
