Hello all!  
Greetings.

Please:

**Scenario:**  
I getting a \<\<\>\> response for a .js file and I need it as a string.

**Server:**  
Coyote, not sending Content-Type header

**What I`m trying to achieve:**  
Within this .js file there is some encryption methods. I need to use it generate encrypted Strings and use it for several subsequent requests.

So far, I`m trying to transform the response with **.transformResponse** which seems to work in a different way that I`m expecting.

I’m using gatling **2.2.4**

Thanks in advance
