Incorrect content length sent

[floyd-fuh]

When I run https://github.com/pajswigger/content-length-fixer I will get alerted that ActiveScan++ sends incorrect Content-Length headers when it is doing a test request with application/xml as Content-Type, when it is using an Accept header of ../../../../../../../../../../../../../e*c/h*s*s{{ or using the Content-Type header of ${#context["com.opensymphony.xwork2.dispatcher.HttpServletResponse"].addHeader("X-Ack",2273*5098)}.multipart/form-data
