Class NewRelicTag

java.lang.Object
jakarta.servlet.jsp.tagext.TagSupport
org.deltava.taglib.CSPNonceTag
org.deltava.taglib.content.NewRelicTag
All Implemented Interfaces:
jakarta.servlet.jsp.tagext.IterationTag, jakarta.servlet.jsp.tagext.JspTag, jakarta.servlet.jsp.tagext.Tag, Serializable
public class NewRelicTag extends CSPNonceTag
A JSP tag to inject NewRelic browser instrumentation with a CSP nonce. Because this injected JavaScript can easily overflow the JSP output buffer (which prevents the CSP header from being emitted) this tag has a start and end. The start sets the relevant CSP headers, while the end tag actually emits the script (with the expectation that the CSP header has already been written to the response).
