7. Our server returns the page to you

So, by now, we have a nice new webpage showing your modified text, and containing all the links to modified pages - as appropriate. All the PHP processing has finished, your page is completely sorted. So what next?

• The server issues an instruction in HTTP (you know, that wonderful bit at the start of webpage addresses does actually mean something), and the instruction should begin:

  HTML/1.0 200 OK
  

• Once the above instruction has been sent, the browser knows that the page was successfully sorted out and that the rest of it is on the way. The browser and server communicate with each other, telling each other when bits have been sent and bits have been received. This is all done transparently by the browser and the ISP.
• Once it's all there, your browser just displays the webpage on the page as a pretty nicely formatted page... and everythng is ready for the next time...
