I would like to play back for file with query string in a url because it has its authentication token associated with it. but when I tried to do 

${http_get(http://ip:port/file.mp3?auth_token=abcdefgh)} 

freeswitch complains about Invalid file format. I thin

I am using "FreeSWITCH Version 1.2.0-rc2 (1.2.0-rc2)". Any subsequent version are compatible of play this kind of urls or Am i missing out something.

Thanks,
