[OpenLayers-Users] OpenLayers.Protocol.HTTP and Asynchronous request

[Diego Guidi]

I don't understand, you can simply put the code inside a function and
then call this function in the callback.
syncronous ajax requests (where A is for Asynchoronous) are "evil", if
you need to use this stuff, you're made a mistake.
