问题
Does Apex/Visualforce allow a URL which is stored as string in apex and run it in web browser in background.
Actually, that url is returned from a Docusign RestAPI callout for posting the envelope into "correction" status. The Envelope correction Status is not activated until i manually paste the url (link) in to a web browser and run it.
Does anyone know how to run a url programatically in a web browser through Apex/Visualforce in background ?
(or)
Is there anyway that i could activate the "correction" status of envelope in Docusign other than running the URL in web browser?

As I understand your question(s), the simple answer is NO/YES, but let me break it down:
- Run String URL from Apex - Yes - See pagereference
https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_system_pagereference.htm
- Can you run a URL in Background - Yes you can use HTTP class
https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_classes_restful_http_http.htm#apex_classes_restful_http_http
Can you run a DocuSign correct URL in Background - NO, the URL you get back requires the Browser for rendering and user UI interaction.
Other Way - YES via the DocuSign REST API you can correct the envelope if it has not been completed or the signer has not completed their signing action. Also I have lab I created to demonstrate this on Amazon if you are interested in a step by step example of DocuSign correct.

SAMPLE HTTP PUT via DS REST API below for existing an envelope:
PUT /restapi/v2/accounts/437977/envelopes/ed3be3c1-be06-41c2-c68c-10ddccbd655e/recipients
Host: demo.docusign.net
X-DocuSign-Authentication: {"Username":"yourdsemailorID","Password":"yourpasswordorDSapipassword","IntegratorKey":"yourDSintegratorkey"}
Content-Type: application/json
Accept: application/json
{ "signers": [ { "recipientId": "1", "name": "David W. Grigsby (corrected)", "email": "youremail@yourdomain.com" } ] }
