IRD - check if vxml exists

[vma]

Hi,

Anyone knows if there is anyway to check if a vxml is available on the server before calling the application? I need to play a prompt before calling the app and I don't want to play it if the vxml is not there.

Regards,
vma

You can use the HTTP block and try to GET the content from the web server, if you recieve any valid input you will be sure that the document is available. In other cases, you should suppose web server is out of service. BTW: This can be achieved by using "alternate/backup" webserver.

Hi Kubig,
I guess you mean Web Services block with HTTP option, right? I will give it a try and see how it works.
Actually the vxml is provided by Spitch and the customer wants Speech Recognition to be enabled only on those specific services where the vxml is available rather than being able to enable it from config.

Thanks!

Hello,
I have tried the Web Service block
Request: HTTP
Web Service URL: http://myserver/myfile.vxml
Method name: GET

The URS HTTP logs says the request is successful:
[code]
05/17/19@14:18:51.506: [HTTP Client 0000000000c96780] Received 2715 bytes from server on socket 508:

Still in the URS log I get an error and the returned vale is empty:

Anyone knows what am I doing wrong?
Thanks!

Looks like nothing wrong by itself.
Most likely it is simply Content-Type vxml is not allowed.
Supported content types I think are text/... and application/....

Also you can rely on returned error code.
If web service object return no error or error is 0022 No data (checked with Error segmentation switch on error exit of web service then some web service actually returned something. Real error is when error code is 0013.
