This change adds a new
appendHeader
internal method toRequestTemplate
allowing for already resolved headers to be added to the resolvedRequestTemplate
preventing duplicate expression processing by using another new methodHeaderTemplate.literal
andHeaderTemplate.appendLiteral
respectively.I chose this route as it isolates the change to be applied only after the original
HeaderTemplate
has been resolved. While it does expose new publicHeaderTemplate
APIs, I feel that is an OK trade off, allowing a new escape-hatch for situations where URI template processing is not acceptable for Header values.
