[umairarshadbutt]

this code is giving whole site sitemap, but i need to restrict some pages which can not be rendered. any solution?
for example

http://localhost:8820/contact/thank-you.html
2013-09-24

It should not be generate in the sitemap.xml

One solution would be to add a custom metadata header flag/value and filter out content based on the value.
