Subject [jira] Created: (AXIS2C-1480) Improve performance of reading HTTP headers

Improve performance of reading HTTP headers

                 Key: AXIS2C-1480
             Project: Axis2-C
          Issue Type: Improvement
          Components: transport/http, util
            Reporter: nadir amra

Currently, in file src/core/transport/http/sender/http_client.c, when processing HTTP headers,
we read the data 1 byte at a time.  This is too inefficient and performance intensive, since
each read means a read to the TCP/IP stack. 

The proposal is to improve the stream utility support so that one can specify a minimum number
of bytes to read.  So that when a read comes down that is less than the minimum, we read the
minimum into a stream buffer and then copy the requested read length into caller buffer. 
So next time stream is read, and there is data in the stream buffer, the data is returned
without having to do a socket read. 

We can probably extend this on the stream write-side as well.
