encode request for get

//encodeURI and encodeURIComponent do not encode encode parenthesis 
let graphQlQuery = 'query{sessions{title},getStarWarsPerson(id:1){name}}'
let queryStringForGetRequest = encodeURI(graphQlQuery).replace('(', "%28").replace(')', "%29")

• serverside
• make graphQL GET queries smaller

Query limit: Although officially there is no limit specified by RFC 2616, many security protocols and recommendations state that maxQueryStrings on a server should be set to a maximum character limit of 1024. While the entire URL, including the querystring, should be set to a max of 2048 characters.

• FIX: Send SHA-256 hash of query string to be executed
