I have many compounds with ID’s and other properties going through a pipeline. I need to get additional properties from a web service using HTTP Connector. For one or several compounds I can get the properties by using a URL source like this:

http://blablabla/compound_id1,compound_id2,.xml

How can I pass compound_id into Source parameter of HTTP Connector?

If I create a new property or a global property @link, HTTP Connector would not take it and would give the following error:

“Not a valid request for a file reference that is not a URL: @link”
