When a publishing request is issued by some electron or embedded webkit applications, the request may be treated as CORS request.  
A preflight request (OPTIONS request) will be sent before the real request during performing the request.  
Currently write.as responds 404 error for OPTIONS preflight requests.

Please support CORS preflight requests.

I think supporting this feature would actually fix my Blazor WASM apps.

We can absolutely do this. Are there any endpoints in particular we should start with for you both?

I prefer ‘/api/posts’. My application is to publish posts from front end code. So enabling OPTIONS method for ‘/api/posts’ will be great help to get my app done.  
Thanks.

Thanks for considering this. Looking at the code for my Blazor apps, my most used endpoint seems to be this one:

`api/collections/{0}/posts?page={1}`

`{0}` here is the write.as alias and `{1}` is the page number.
