Dynamically Enable/Disable Web Service at Run-Time

[NathanDII]

Is it possible to enable and disable LabVIEW Web Services in my application at run-time?  If for example, I build an application with the web services, I have cases where I would like to prevent any access via the web service.

I was unable to find any Web Services VIs that appear to do what I'm asking.

Hi NathanDll,

You should be able to do this.  Check out this KnowledgeBase article:

Can I Programatically Start and Stop the LabVIEW Web Server?

Let me know if this is not what you are looking for!

The method that Nick mentions should work - but if you only want to disable certain web services or certain VIs/URIs - you could have the web service VIs return invalid/blank data depending on a condition in your application (e.g. a ISServerActive? shared/global variable). For example, you get have the VI return a different HTTP status code (using the Web Service VI) if you don't want to accept the request (e.g. 404 not found, 401 unauthorised, 403 forbidden etc.).

Thanks guys!  I can't believe that I didn't find that article through my searches.  I guess it might be because I was searching for "services" instead of "server".
