com.aoapps.servlet.filter.TrimFilterResponse

All Implemented Interfaces:

HttpServletResponse, ServletResponse

public class TrimFilterResponse
extends HttpServletResponseWrapper

Filters the output and removes extra white space at the beginning of lines and completely removes blank lines. TEXTAREAs are automatically detected as long as they start with exact "<textarea" and end with exactly "</textarea" (case insensitive). PREs are automatically detected as long as they start with exact "<pre" and end with exactly "</pre" (case insensitive). The reason for the specific tag format is to simplify the implementation for maximum performance.
