Re: [Pi3web-users] External redirection

[Dharmesh S. <for...@ho...>]

Hello Holger,

Thanks for the feedback.
I will explore using - SF_NOTIFY_PREPROC_HEADERS.
Any hints/leads for external (via the browser, location of the target e.g. 
at another web server) redirect.

Thanks,

Dharmesh

Subject: Re: [Pi3web-users] Help on ISAPI Filter for SF_NOTIFY_URL_NOTIFY
Date: Wed, 25 Feb 2004 19:44:41 +0100

Hello Dharmesh,

do you want to perform an internal (URL with physical location of the target 
within the server) or an external (via the browser, location of the target 
e.g. at another web server) redirect? For the first case refer to this link: 
http://www.codeproject.com/isapi/isapiredirector.asp

In this MFC-example they catch SF_NOTIFY_PREPROC_HEADERS events and simply 
change the URL. This is done, before the server processes the headers, i.e. 
maps the URL to a physical resource path.

(I don't know, if the following is necessary, but in order to get 
SF_NOTIFY_URL_MAP events you must invoke the filter DLL prior the Pi3Web 
handler object, which completes the mapping phase, this is per default the 
'Start' object. Or you must supress the completion of the 'Mapping' phase by 
the handlers invoked prior the filter.
This is the way, how Pi3Web handles processing of the separate request 
phases: Each handler configured in the server logic object will be called, 
until one sets the status of the processing of the phase to 'completed'.)

Holger
