Hi Sven, when running a Zinc Server ZnServer startDefaultOn: 8080. the server currently reveals the framework, the framework version and the Pharo version the server is running on as part of the HTTP communication. For instance (ZnEasy get: 'http://localhost:8080') headers at: 'Server' would give Zinc HTTP Components 1.0 (Pharo/7.0) in the Server Header. While this is nice for debugging and during development this can be a problem in more secured/pentested environments where usually specific headers are turned off to not give specific informations to an attacker (to allow him to find vulnerabilities of specific versions or servers). While headers could be changed rewritten in front-ends or load balancing servers we can not assume that Pharo images work as backend server always. Webservers like Nginx, Apache, IIS, Express in JS, PHP and other allow to disable/modify these headers. Using the attached changeset it is possible to modify the Server header and customize it: ZnHeaders serverString: 'MoreSecureServer' If the server string is not customized the default server string is used as before. We should make sure this is integrated into Pharo 7 but also into the Zinc framework. I opened a bug https://pharo.fogbugz.com/f/cases/22317/ZnHeaders-should-allow-custom-or-emp... As Zinc is also managed externally how should we proceed? Thx T.
