Question: use only GET but avoid send full query and combine GET and POST

[havran]

Hello.

1. It's possible use only hashed queries, without send full query (even of client side error is triggered)? I want prepare and store all hashed query on server myself, without use 'automatic query resend'.

2. I use useGETForHashedQueries: true and if persisted query is not stored on server side client try send full query (which is big) through GET (which create error fastcgi request record is too big on NGINX). It's possible configure link to send full query through POST and hashed query through GET?

Thanks.

Ok. I found answer to second question (Angular, typescript):

  private getCmsClient() {
    const cache = new InMemoryCache({
      addTypename: true,
      fragmentMatcher: fragmentMatcher,
    });

    const httpLink: HttpLinkHandler = this.httpLink.create({
      uri: 'http://web.local/graphql',
    });

    const queryAsPostMiddleware: ApolloLink = new ApolloLink( (operation: Operation, forward: NextLink) => {
      const context = operation.getContext();
      if (context.http.includeQuery && context.method === 'GET') {
        context.method = 'POST';
        operation.setContext(context);
      }
      return forward(operation);
    });

    const persistedQueryLink: ApolloLink = createPersistedQueryLink({
      useGETForHashedQueries: true,
    });

    this.apollo.create(
      {
        link: from([persistedQueryLink, queryAsPostMiddleware, httpLink]) as any,
        cache: cache,
      },
      'cms',
    );
  }

queryAsPostMiddleware make all queries sent always with POST.

I think answer for first question is simple return null on same middleware instead of return forward(operation), am I right?
