php - what is Via in HTTP Response and how to remove it? -

I have requested a curl a PHP file on my server From my machine and it gives the following reaction.

  HTTP / 1.1 200 oak content-length: 317 Content-Type: Application / Jason Server: Microsoft-IIS / 7.5 Last modified: Wed, 19 February 2014 11:30:16 GMT Via: 1.1 SC10100_83_75 Connection: Keep-alive date: Wednesday, February 9, 2014 12:00:47 GMT  

The problem is, it seems that my request is not caching and returning to the latest prices is. I suspect that this is through wider (read that it is about proxy). What is this and how can I remove it?

looks like this - it indicates that you are rooted through a proxy - However - this is just information - you need to make sure that the caching headers are being set up correctly so that the proxy can take the correct action.

No caching header is currently being installed on your request.

If you do not want to cache it - then set the following title:

  cache-control: no-cache
