[OpenLayers-Users] Requesting zip data using OpenLayers.Request.GET. bug ?

[Kwong Hu Kiu]

How am I crossposting ? 
I thought this 'might' be a bug. That's why i sent it to the dev list.
Is this wrong ?

Anyway... 

No, you don't understand my question.
Once users clicked on a button called 'Download zip'. 
The wms-server will send a respond together with a zip file. 
I thought this will work if Openlayers.Request is behaving the same way as requesting from the browser.
