Hi, I am hitting a limit in one of my implementation: requestformkeyslimitexceeded , which generelly come when we implement continuation with vf pages. So max # of keys in http post form should be 500.
Can you please advice if you happen to see this error anytime and how to approach for this. It the page which needs redesign or its http request which is exceeding some size limits?

Will we be able overcome callout time limit exception from this approach? If the callout is taking more then 2 mins to process.

How can I initiate Continuation through Apex instead of Vf page. Let’s say I want to initiate RequestService from another method, can we do that??

“We can accomplish this by using Actionsupport”, Sir I think actionsupport make synchronous calls to page controller? If i am wrong? Please let me know.

In reply to Manav.

Hey Manav, For chained continuation, you would need to write test classes separately for each call. This is official Salesforce documentation on how to write test class – https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_continuation_testing.htm
