Content-Length Calculation in the Response object.

Hi,
I am setting the binary content to the response object.
It is an input Stream object to Response.entity(InputStream Object).
 
Does wink calculate the Content-Length after reading the entire Stream .
 
When I am using  the RestClient does the Content-Length will be provided in the Response Header by apache wink provider classes or Do i need to calculate the Content-Length in resource class and add to Response.entity(InputStream Object).header(Content-Length,size)
 
Thanks,
Srinivasan.V

Hello,

You will need to set the Content-Length header yourself in the server code.
 We do not read the entire InputStream and calculate the size.  Imagine if
that InputStream was 1GB of data;  we shouldn't buffer 1GB of data in memory
or anywhere else and we can't "unread" the InputStream.
