CORS request won’t trigger making cache?

    Hi there, I found that a CORS request make by the fetch seems like won’t trigger the cache to be made?

    I have set the these headers to make sure cors will work

    
access-control-allow-headers: Authorization, Content-Type
access-control-allow-origin: *

    and in the settings panel I have set “Force Public Cache URIs” to ^/graphql

    yes, it gets a response with 200 status code, but the payload is empty, not even a single letter. I can confirm that the response header with x-litespeed-cache:hit which shows it is a cached response, but with no contents.

    I could confirm that it works if I just copy and paste the request URL made by the fetch to the browser’s address bar(which means it works with the same domain).

    The fetch will send a OPTIONS request before it can send a GET request, so I’m guessing maybe LiteSpeed cached the OPTIONS request instead of GET request..?

    I’m making an API request(GET method) from another domain to an end point of the domain which using this plugin. I want to know if this is a bug or intended?

  • Hi @yaquawa

    From the behavior you described, it’s possible that the OPTIONS request being cached instead of the GET request. I can tell that from the post, you have the capability to do further digging and troubleshooting. Could you please check the cache plugin log or even the lsws log to figure it out?

    Frankly speaking, we rarely had this scenario happen to us in the past. If you could verify that it would be great.

    Hi @usabe , thanks for replying!

    I’m not an expert of LiteSpeed Cache, I’m just using a rental server that using LiteSpeed.

    Could you tell me how to setup LiteSpeed Cache to not cache request except GET and HEAD method? (Should I modify the .htaccess?)

    Hi,

    by default it only caches with GET request

    you can check source code here

    if ( $_SERVER[ 'REQUEST_METHOD' ] !== 'GET' ) {

    Hi,

    you can simply enable the debug log , then see what log says about that request , or why not cached on that request

    sorry for the late replying, I have tried output the log, this is what I got.
    Do you see any problems in this log? looks like it was caching the OPTIONS method?

    I also tried to find the log you mentioned at here:

    https://github.com/litespeedtech/lscache_wp/blob/v3.6.4/src/core.cls.php#L331

    but I can’t find any text matches [Core] CHK html bypass: not get method, does this means this is a bug?
