Make the network and the custom protocols transparent for
Fetch resources through HTTP, FTP, RES, MK, ABOUT, ALP and all the
other protocols you may have, Send data/files through them, post forms
autmoatically, exchange data between servers, build applications with
ultimate network connectivity - that is the idea.
NetProbe is a protocol independent ActiveX intended for
sending and retrieving information through any protocol registered on
the local system. It was tested with standard protocols like http,
ftp, file and with custom protocols like res, mk (MS HTML
Help protocol), alp (Active Local Pages) and others. So
NetProbe is not just a tool for internet, but also universal tool able
to fetch/send information through any available protocol no matter if
it is a network oriented protocol (such as http) or a local processor
(such as alp and mk).
Example tasks that can be done with NetProbe:
Fetching information from a CHM (HTML help file) file and
embedding it into the pages generated on the WEB server (with a few
lines of ASP code)
Sending requests POST, GET, PUT to remote servers and working
with the returned data
Using external protocol engines as content servers in
applications running on the desktop or on the WEB server. For
example an application (or even ASP page running in IIS) may request
ASP page to be executed by the ALP engine and do something with the
Fetching information from the internet. The NetProbe runs the
same way as Internet Explorer and is able to fetch everything IE is
able to download.
Synchronization/data exchange between machines/servers. For
example an ASP page can download news from other servers (in any
format) and select something to show.
NetProbe supports features required sometimes by the protocols -
such as authentication, request/response headers manipulation. The
requested information can be accessed as string or binary data as
appropriate. Using additional controls (such as Storages and Files from
the ActiveX Pack1 or a XML parser) NetProbe is able to provide all
the required services for network or network-like communication and real-time data
exchange. The data can be posted/sent through NetProbe in user-defined
formats - for example if the application wants to post a form or
NetProbe comes in two forms - both and freethreaded.
The applications are able to create and manage pools of NetProbe
objects and are provided with certain synchronization services (for
the freethreaded case mostly). For example an ASP application can create
several NetProbe objects and keep them in Application variables. Then
the ASP pages are allowed to wait/occupy a NetProbe object and use it.
These features allow the application to optimize its network functions
depending on the expected transfer and requests count.
The applications that use NetProbe can set Timeout which means in
this case "time limit" for the requested operations.
This allows the server applications to control the time spent for the
network operations and response to their clients in time. The actual
timeout value depends on the system settings of the protocol used and
And one simple demo - more can be found in the documentation and
the samples in the archive.
Let us fetch a resource first. We need to create and configure the
object and send a request.
Set np = Server.CreateObject("newObjects.utilctls.NetProbe")
If np.Request("http://server/resource") Then
If np.ResponseMIME = "text/plain" Then
' Do something with it - for example display it
' Not the content type we have expected.
