Bing maps proxy script example..?

[andr01dm]

Hello.

I'm creating a UMap app using Flex, and have learned that in order to
create routes with Bing I need to enable MapPointProxy, which in turn
needs to point to a proxy service PHP script on a web server.

Can anyone give me an example of this PHP script?

Thank you.

Here is the sample proxy file http://umapper.googlegroups.com/web/msproxy.php
(or see Goup's files)

Can we still use the proxy file approach?(with bing token....). If so can you re-post the sample proxy file?

I would prefer to use the approach with the bing key only....but that is only in the API 2.0 right?...and its not released?

Thanks

Here is msproxy.php from the former umapper googlegroups files repository.
