[fw-general] ZF caching output. Howto disable this so can chunk serve file.

[Julian Davchev]

Hi,
I am trying to chunk serve file using fopen,fread,fseek etc.
Problem I think I am having is that ZF is caching the output...and I get
out of memory instead of using constant memory for no matter how large
file I serve for download.
Using MVC part have action for this download.... have disabled renderer
and layout.
Please let me know how can disable caching of page..I am pretty sure it
occurs.
