Sometimes I want to get values without using boundaries, For example to extract only values from property file I don't want to use regular expression, which is heavier on performance I suggest allowing empty left/right boundaries to enhance faster extraction of response without defining one or both boundaries First ask https://stackoverflow.com/questions/50811528/jmeter-boundary-extractor-where-right-boundary-is-end-of-line
Asked also about getting all response (without boundaries) https://stackoverflow.com/questions/50940846/extract-the-body-of-a-response-in-jmeter-and-use-in-other-requests
