How to send a response with HAProxy without passing the request to web servers

由 不羁岁月 提交于 2019-12-20 12:30:16
问题 The server is receiving thousands of OPTIONS requests due to CORS (Cross-Origin Resource Sharing). Right now, every options request is being sent to one of the servers, which is a bit wasteful, knowing that HAProxy can add the CORS headers itself without the help of a web server. frontend https-in ... use_backend cors_headers if METH_OPTIONS ... backend cors_headers rspadd Access-Control-Allow-Origin:\ https://www.example.com rspadd Access-Control-Max-Age:\ 31536000 However for this to work I

Chrome, no response data after OPTIONS request?

由 拈花ヽ惹草 提交于 2019-12-20 11:32:22
问题 I'm using CORS to fetch some data from an API. All was working well until Chrome update launched a day ago. Now after an OPTIONS request the subsequent request always returns with no response data. If I click a button quickly twice it will show on the second request (the same one) since it's not making the pre-flight call. I've re-installed and disabled all extensions, no idea what's going on here. Is anyone else experiencing this? EDIT note that the no response is directly from the devtools.

Unity3d + WebGL = Cross-Origin Request Blocked

问题 I was wondering if anyone could briefly explain how you get the REST api to function with Unity3D project built to WebGL platform. I just started changing my project over today thinking I could use REST to get around Parse's use of threading in a WebGL build I need to make. I promptly ran into the CORS problem though and not being familiar with it, I am unsure how to go about fixing the issue. Currently I make use of the WWW class to send the request from within Unity.

Cross-Origin Resource Sharing (CORS) - am I missing something here?

由 大城市里の小女人 提交于 2019-12-20 08:41:52
问题 I was reading about CORS and I think the implementation is both simple and effective. However, unless I'm missing something, I think there's a big part missing from the spec. As I understand, it's the foreign site that decides, based on the origin of the request (and optionally including credentials), whether to allow access to its resources. This is fine. But what if malicious code on the page wants to POST a user's sensitive information to a foreign site? The foreign site is obviously going

问题 We are trying to host api spec yml file in our svn repository which is hosted on another server.
