"Redirecting into HTML page" - mule

Question

I have a flow where I am trying to load a HTML page if successfully login or fails. Flow is working but while doing POST job on browser side it's not redirecting to the loginSuccessful.html or login/loginFailure.html.
<flow name="GetLoginPage">
<http:listener config-ref="HTTP_Listener_Configuration" path="/login" allowedMethods="GET" doc:name="HTTP"/>
<parse-template location="login/index.html" doc:name="Parse Template"/>
</flow>
<flow name="Dologin">
<http:listener config-ref="HTTP_Listener_Configuration" path="/login" allowedMethods="POST" doc:name="HTTP"/>
<logger message="trying to login!!!!!!!!!!!" level="INFO" doc:name="Logger"/>
<choice doc:name="Choice">
<when expression="#[payload.username == "mule" and payload.password == "mule"]">
<logger message="login successfully!!!!!!!!!!!" level="INFO" doc:name="Logger"/>
<parse-template location="login/loginSuccessful.html" doc:name="Parse Template"/>
</when>
<otherwise>
<logger message="login failed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" level="INFO" doc:name="Logger"/>
<parse-template location="login/loginFailure.html" doc:name="Parse Template"/>
</otherwise>
</choice>
</flow>

Answer 1

I took the liberty of creating my own payload in JSON and added the payload values from above:
{
"name": "mule",
"password": "mule"
}
Then, added a data transformer from JSON to Java, then I mildly adjusted your conditional test to eliminate the encoded quotes and replaced them with single quotes:
payload.username == 'mule' and payload.password == 'mule'
And the choice router correctly to pick up my test files with the parse template.
