Hello,
 
I'm writing a VXML application which does two HTTP POST calls to a Generic Handler writen in C#.
In the VXML script I'm calling the same URL twice, but the second time with more parameters.
The weird thing is that the second time the call is executed the values of the parameters are double and are comma seperated.
 
I have this configured under an incoming dial-peer as a service.
 
Cisco configuration:
 
http client cache refresh 1
ivr prompt streamed http
vxml version 2.0
 
dial-peer voice 2000 voip
service vxmlapplication
 
Why is this happening?
 
Thanks,
 
Grant

How does this work if you use vxml 2.1 and the VXML 2.1 <data> tag?

[hemal.mehta]

The data tag from VXML 2.1 is typically used to fetch XML data and then parse it. For cisco data you can call any URL and post data to it and get a response back from the server.

Hemal,

Does this mean the <data> tag can be used for an HTTP post to a server, and then fetch XML for parsing? 

Second, I've found that the <data> or <cisco-data> tag don't support Basic Authentication, example given, where the server requires a username and password:

<var name="URL" />

<assign name="URL" expr="'http://username:password@IP/Service'" />

<data name="MyName" srcexpr="URL"  namelist="varA varB"  method="post" fetchtimeout="50000ms" />

How does Cisco recommend handling Basic Authentication for <data> HTTP POST requests?

Have you see this?

Bill,

. I have used data tag to fetch a xml doc based on certain criteria. So you can pass in the name for the dom. So for example I could have something like

Hope that makes sense.

Hemal,

Please type that again.  There is nothing on your comment for your example hemal.mehta.

Thank you,

Sorry Bill.  Here you go...

Bill,

  .   I have used data tag to fetch a xml doc based on certain criteria.  So you can pass in the name for the dom.  So for example I could have something like

<address>

   <streetname>Berry dr</streetname>

   <streetnumber>246</streenumber>

<address>

<data name=”address” src=”address.xml”>

<!----Put java script code to retrieve the xml values -à

<script>

</script>

</data>

Hope that makes sense.
