[Asterisk-Users] Re: AGI GET Variable Problem

[Kenige Ho]

Dear All,

Never Mind, I have solved the problem.  It seems that you should clear the
buffer for any 'waiting' response or else you will be getting an empty '200
result=1' response.  So be sure to read, before you write in php agi script
to ensure that you will get a proper response.

Kengie
