You can get some degree of server push if you need it:

   In the HTTP protocol the webserver has no authorization to perform

   to browsers perform advanced actions in order
   to generally improve user experience.

   If you want a peace of page that auto refreshes, it must be achieved
   by GET and POST requests through a _javascript_ on the command.

   I'd suggest you to read a good HTML+Ajax book.

       I asked because I use lwIP and the httpd-server raw to implement
       my web server. I thought that maybe someone else has already
       done what I'm trying to do, that is send, through lwIP, a web
       page to a browser without an explicit "get" command from the
       browser itself. the more straight solution would be that the web
       page asks a refresh every N seconds, like the example in
       freeRTOS, but I'd like to avoid it and let the web server hanlde it

           In which respect is this question lwIP-related? There's

           Hi everyone!

           I have a web page that shows the content of some memory
           locations that I use as registers. I'd like that when  the
           value of some of these registers changes, the web server
           will send the updated page and refresh the browser.

           how can I do it?

           up to now, my web server only responde to "GET" command
           from the browser

           Thanks, Rocco ^_^
