I am unable to run the examples, specifically "Hello", with IIS 7.5. When I compile with the default wthttpd, everything works fine and the examples run as expected.

When I compile (in a separate directory) for ISAPI, with "cmake -DEXAMPLES_CONNECTOR=wtisapi ..\" everything compiles fine too, but I can´t get the example running.

I followed exactly the instructions in the online documentation "ISAPI on Microsoft IIS" and "Installing Wt on MS Windows".

Whe I direct Firefox to "" I get the following error information:

Error Summary:

HTTP Error 403.14 - Forbidden

The Web server is configured to not list the contents of this directory

Detailed Error Information:

Notification ExecuteRequestHandler

Handler StaticFile

Error Code 0x00000000

Requested URL

Physical Path C:\projects\wt-3.1.11_DLL\examples\hello\

Logon Method Anonymous

The DLL and the configuration file (unchanged) is located in "C:\projects\wt-3.1.11_DLL\examples\hello", together with "hello.wt.dll.ini" containing:



My system is VS 2010 + Boost 1.47.0 + wt 3.1.11 + cmake 2.8.6

Am I missing something?

If I remember correctly, I always had to surf to the .dll file. So don't you have to access http://localhost/hello/hello.dll?

When I surf to "" IIS offers me either to save or to open the DLL. It treats the DLL as a file, not as an ISAPI-Extension, that is it does not execute it.

Please update your ISAPI-documentation.

- After I set "Enable 32bit Applications" to true in "Application Pool Defaults" I was able to run the example. My system is Windows Server 2008 R2 (x64) with IIS 7.5.

- Your docu says to set the "Regular Time Interval (minutes)" to 0, but this is not possible if you don´t set "Idle time out (minutes)" to less than "Regular Time Interval (minutes)" before, that is you must set it to 0 too . But this setting is nonsense.

Now I can start the "hello" example, but I run in another problem.

I get prompted for my name, when I enter a name and press the button, nothing happens, that is no greeting appears, just in the right corner of firefox a red message "Loading" appears and nothing happens.

Any ideas?

Thanks in advance,

I'll have to look into this. Do you see any errors in firebug (or whatever the debugger for your browser is)?
