Same question
We are also experiencing this issue. As we do have a quite huge amount of different users, our backend(running on cross origin) has to handle mainly cors requests(yes, we are setting cors caching headers).
I tried setting content-type to "text/plain" in createHttpLink-options. This caused no more preflight requests. At the same time it prevents persisting new queries via post-request. In this case we need to have different content-types for get and post requests each.
I'm using this amazing package for persisted queries and
{ useGETForHashedQueries: true }
.Everything works good but I think something is happening if I use ApolloServer with CORS (which I hate and in the future I think I will avoid them with something like a proxy or what will be).
Now the problem is I see some
GET
s withPREFLIGHT
OPTIONS
calls.I think this is happening because of
content-type: application/json
inRequest Headers
.Can we switch this
Content-Type
to ex.text/plain
.I'm newbie, I don't know if there is a security concern changing the Content-Type.
