Livereload not working with projects hosted on local Server with Content Security Policy (CSP) enabled ------------------------------------------------------------------------------------------------------ Key: JBIDE-20771 URL: https://issues.jboss.org/browse/JBIDE-20771 Project: Tools (JBoss Tools) Issue Type: Bug Components: livereload Affects Versions: 4.3.0.CR1 Reporter: Ilya Buziuk Assignee: Ilya Buziuk Fix For: 4.5.x Attachments: csp.png This problem might be treated as an edge case from the first glance, but actually it might have a sufficient impact on Livereload in the short run. *CSP* is sort of security policy which complements *CORS*. However, Content Security Policy and CORS are two separate things. CORS is the web service declaring which apps are authorized to call the service. Content Security Policy is kind of the opposite: it's the app that declares which services can be called. Basically, [Content Security Policy|http://www.html5rocks.com/en/tutorials/security/content-security-p...] is supported by new versions on major browsers in order to prevent Cross-site scripting (XSS) attacks. However, this policy restricts the usage of LiveReload to the certain extend. Steps to reproduce: 1) Create default *jboss-as-kitchensink-html5-mobile* 2) Add CSP meta tag {code} <meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval' ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"> {code} ^ allow to use jquery (other stuff is hosted locally) 3) In Preferences (General -> Web Browser) add newest version of chrome and set as default 4) Run the project on the Local Server (Tomcat) 5) In the Server View right-click on the hosted project -> Show In -> Web Browser via LiveReload 6) Edit and save index.html 7) ERROR: Livereload is broken - CSP has prevented *livereload.js* injection !csp.png! N.B. LiveReload will work with the file protocol (right click on index.html -> *Open With* -> *Web Browser with LiveReload*) even with CSP enabled, cause in this case livereload.js is hosted on the same port (35729 by default) as the whole project
