You need to extract path to "View" page after logging in into a JMeter Variable and use it as a parameter in the relevant request. The most commonly used test element for it is Regular Expression Extractor. Something like:

• Log In
  • Regular Expression Extractor -> Get "View" page URL
• Open "View" page using URL from the Regular Expression Extractor
