Override IIS Maximum upload size [max upload size in asp.net]
by default IIS enables you to upload 2 megabytes and i couldn't seem to figure out how to change that using Internet service manager snap in
but i found this on msdn and it's working perfectly fine
alll you have to do is add this node right under <system.web> section in web.config
1: <httpRuntime maxRequestLength="size in KiloBytes"
2: executionTimeout="seconds"/>
and i managed to upload quite large files.
