FTP
24.2 FTP
Caché includes a class, %Net.FtpSession, for establishing a session with an FTP (File Transfer
Protocol) server from within Caché and download and uploading files.
24.3 HTTP
Caché includes a class, %Net.HttpRequest, for making HTTP (Hyper Text Transport Protocol)
requests from within a Caché application. The response to such a request is wrapped within
a %Net.HttpResponse object.
24.4 URL Parsing
Caché includes a utility class, %Net.URLParser, for parsing URL strings into their component
parts.
This class is quite simple, it contains one class method, Parse, that takes a string containing
a URL value and returns, by reference, an array containing the parts of the URL subscripted
by part name. For example:
Set url = "http://www.intersys.com/main.cspQUERY=abc#anchor"
Do ##class(%Net.URLParser).Parse(url,.components)
Upon return, components will contain an array of the parts of this URL:
Element
components(“scheme”)
components(“netloc”)
components(“path”)
components(“query”)
components(“fragment”)
Value
http:
www.intersys.com
/main.csp
QUERY=abc
anchor
Description
The transport scheme specified by
this URL.
The network address of the URL.
The file path of the URL.
The query string associated with
the URL.
The fragment (following the #
character) for the URL.
