Re: Invoking a remote webservice using JSON

[Bradley Stone <bvstone@xxxxxxxxx>]

Bill,
Here's an example of using GETURI.

This example returns the result to the program, but it can also be saved to
a stream file with only a couple extra simple parameters.

Both the variable and the stream file are easily plugged into YAJL in order
to parse the results.
