Class MadvocResponseWrapper

java.lang.Object

javax.servlet.ServletResponseWrapper

javax.servlet.http.HttpServletResponseWrapper

jodd.madvoc.MadvocResponseWrapper

All Implemented Interfaces:

javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public class MadvocResponseWrapper
extends javax.servlet.http.HttpServletResponseWrapper

Madvoc HTTP Response wrapper. It does the following:

• Delays setting of response encoding until response is being used, allowing resetting the charset.

This unifies the behavior of servlet containers. Method setContentType may be called more times, and its on servlet container how to deal with character encodings. For example, if user set content type with following values:

• text/html;charset="UTF-8"
• image/png

the question is would the second call reset the character or not. Tomcat 6-7, for example, does not reset the charset on content type change. In our opinion this is an error since new content type means new charset, as well.
