Hi,
Just in case anyone else has the following issue (unlikely but you never
know) here is the solution I eventually found after I was threatening myself
with a wipe and reload of my laptop.
VB6 to VB.NET web project Port.
We wanted all the code to run under .NET
However we use an ISAPI filter. According to posts my Microsoft bods it is
not possible to write these in .NET.
But it is as long as your ISAPI filter isn't that complex - with a few
drawbacks.
First off create a class that implements IHttpModule and setup the
appropriate bits in web.config.
Next in IIS add a mapping of *.* to be processed by the ASP.NET DLL. This is
done because usually things like
CSS and JPEGs etc... don't get processed by ASP.NET
In inQuire2.NET's case we could have URLs requested like:
http://www.mysite.com/res/3/mystyle.css
Before in inQuire2.COM+ the ISAPI filter would kick in and do a redirect to
another page that would actually
cause the file mystyle.css to be fetched out of the database.
But now with the HttpModule it receives a request as the above and without
redirecting gets the file and returns it.
So hence you have a speed increase because theres no redirect going on and
it's managed code so it can be debugged easily.
Drawback time !
1) The *.* mapping makes the setting of a default document for the site
pointless because this never reachs the site or gets used.
But the big time wasting killer is.....
2) If you close VS.NET 2002/3 and then try to reopen the project it will
then complain that the locations of http://localhost/yoursite and
c:\usr\mysite don't point to the same location even though they do and you
haven't changed anything. The reason for this is because of the *.* mapping
above screwing up .NET's wacky offline cache handshake stuff.
So to get around it you have to remove the *.* mapping before opening the
project, having opened it you can then add it back in.
