There seems to be a change in how salesforce handles subscribing to a push topic with the update to Spring 14.  When we try to subscribe to a push topic with Spring 14 we receive a “403:Unknown Client Error”.  We have not had this issue with previous versions of salesforce.

Streaming Api Steps
1. Authenticate to Salesforce - Success
2. Preform Handshake with Salesforce – Success
3. Subscribe to a Push Topic – Error

The error that we receive is a 403: Unknown Client error. There is no additional information that is passes back in the response.   Why would we receive a 403:Unknown client error.
