how can I use keep alive idle connections for GET requests and new connections to POST requests

[rambabuy]

Hi,

To avoid some Issues I need to create new connections for POST (upload file)
 requests.  
But, If I disable keepalive under upstream I am getting the following error
"  99: Cannot assign requested address) while connecting to upstream,   " 

Is there a possibility to use idle connections for GET requests and new
connection for POSTS requests?
or is there a way to control TCP new connections or to control TIME_WAIT 
connections.

TIME_WAIT connections causes "99: Cannot assign requested address) while
connecting to upstream, "  error


Thanks
Rambabu
