Hi
Yes, you can set a dynamic url with context variables, for example,
Create a context variable called name in context viewer, and then set a dynamic URL:
" http://api.wunderground.com/auto/wui/geo/ForecastXML/index.xml?query="+context.name
And you can load the value of context variable at runtime.
Let us know if you have any questions!

Hi
Where does the value of name come from in your case? db? file? or input by user who call the webservice?
