Hi, I am attempting to access the public usegalaxy.org server using the REST API from web browsers. The question: I am not seeing Access-Control-Allow-* headers in REST API responses. Are browser REST CORS requests supported by the Galaxy servers? More details: Here is an error reported by Chrome during a preflight OPTIONS request for a GET https://usegalaxy.org/api/tools?key=MYREALKEY request. XMLHttpRequest cannot load https://usegalaxy.org/api/tools?key=xxxxxx. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access. The response had HTTP status code 404. The request headers: 1. Accept: */* 2. Accept-Encoding: gzip, deflate, sdch 3. Accept-Language: en-US,en;q=0.8,es;q=0.6 4. Access-Control-Request-Headers: accept, content-type, gs-toolname 5. Access-Control-Request-Method: GET 6. Connection: keep-alive 7. Host: usegalaxy.org 8.
