Answer 1

Given the value is stored in the HTTP Cookie Manager, you can access it using below steps:

1. Add CookieManager.save.cookies=true line to user.properties file
2. Restart JMeter to pick the property up
3. Access the cookie value as ${COOKIE_.ASPXAUTH} where required.

See Using the HTTP Cookie Manager in JMeter article for more detailed explanation of the above steps

Answer 2

In Regular Expression Extractor, under Field to check, please select Response Headers radio button.

To save Cookies automatically, In jmeter.properties file, set as following:

CookieManager.save.cookies=true

Restart Jmeter.

You can access the saved cookies with COOKIE prefix.

example (in your case):

${COOKIE_Cookie_Data} # confirm the same in debug sampler result in View Results Tree

I strongly suggest adding Debug Sampler & View Results Tree, which shows the saved cookie values.
