It's possible to remove the "/*-secure-" sentence from the response of the worklight adapter?
/*-secure-
{"isSuccessful":true,"result":"CC: No subscription found for user :: 11111"}*/
version: Mobilefirst 7.0.0
You can take a look at the answers in this other OS question
Calling Worklight adapter from external app
I believe it is not possible to remove the /*-secure from the response. As responded in that question, it is a feature to avoid XSS atacks.
