Hi cbradbury,

This is probably the most common problem people encounter deploying a Lightstreamer Web Client application using two servers (a Lightstreamer and a Web Server)

The problem is solved with the use of the setDomain method.
You can refer to the linked JSDoc for further details, btw I advise you to read also the README file placed under LS_HOME/DOCS-SDKs/sdk_client_web/examples/StockListDemo/ (look for the "External deployment" section) where LS_HOME is the directory where you unzipped Lightstreamer.zip (or Lightstreamer.tar.gz)

Please note that some issues can arise with the setting of the domain. You can find those issues (and relative work-around/solutions) in the "Known Browser Issues" section of the forums.

Hope that helps
Mone.
