A suggestion Rated 5 out of 5 stars
It's pretty good to see the http headers. If an options to show all http data, such as headers, contents will be much, much better. For some cases, the Http data is also very important. One of the cases is Flex, with Flex HttpService you can see use LiveHttp Headers to monitor the http traffic , but no contents can be shown, this is not like html, you can view the source.
Thanks for the great tool!
