Submit
If set, the command represents a form submission (see below).
The SamePath flag, if set, indicates that pages were retrieved only if they were in
the same path specified in the initial URL. A page is considered to be in the same
path if its scheme and network location components (as defined in Internet RFC
1808,
Relative Uniform Resource Locators)
match those of the initial URL and its
path component matches up to and including the last forward slash (
/
) character
in the initial URL. For example, the URL
http : / / www . adobe . com / fiddle / faddle / foo . html
is considered to be in the same path as the initial URL
http : / / www . adobe . com / fiddle / initial . html
The comparison is case-insensitive for the scheme and network location compo-
nents and case-sensitive for the path component.
If the Submit flag is set, the command represents a form submission. If no
P
(posted data) entry is present, the submitted data is encoded in the URL (an
HTTP GET request). If
P
is present, the command represents an HTTP POST
request. In this case, the value of the Submit flag is ignored. If the posted data is
small enough, it may be represented by a string. For large amounts of data, a
stream is recommended because it can be compressed.
The
CT
(content type) entry is relevant only for POST requests. It describes the
content type of the posted data, as described in Internet RFC 2045,
Multipurpose
Internet Mail Extensions (MIME), Part One: Format of Internet Message Bodies
(see the Bibliography).
The
H
(headers) entry specifies additional HTTP request headers that were sent
in the request for the URL. Each header line in the string is terminated with a car-
riage return and a line feed, as in this example:
( Referer : http : / / frumble . com \ 015 \ 012From : veeble @ frotz . com \ 015 \ 012 )
The HTTP request header format is specified in Internet RFC 2616,
Hypertext
Transfer Protocol—HTTP/1.1
(see the Bibliography).
