Hi, I have a scenario where I need to login to some web app and then reuse the session/cookies in further requests. The basic approach (as presented in Enterprise Pharo book) works just fine client := ZnClient new. client url: 'http://example.com/login'; formAt: 'username' put: 'john.doe@acme.com'; formAt: 'password' put: 'trustno1'; post. client get: 'http://example.com/my-file'. The problem is when I want to change the way response is retrieved. E.g. client accept: 'text/json'; contentReader: [ :entity | STON fromString: entity contents ]; get: 'http://example.com/some.json'. "uh-oh... it still uses STON contentReader" client get: 'http://example.com/homepage.html' Of course I could manually copy all the cookies, however I imagine there is a better approach. Maybe injecting session from one ZnClient instance to another? Thanks, Peter
