Problem with a large embed web page

Hello. I want to control 22 relays from an embed webpage with an arduino mega2560. but they told me the code is too large for send to html. that i have to send by packages.. so. what i can do?

With a certain piece of code the web page loads, if I add more lines it does not load more

static word mainPage()
{
   BufferFiller bfill = ether.tcpOffset();
bfill.emit_p(PSTR("HTTP/1.0 200 OK\r\n"
      "Content-Type: text/html\r\nPragma: no-cache\r\n\r\n"
      "<html><head><title>Control Web</title></head>"

Does anyone have any ideas ??

Maybe you can expand on what an "embed webpage" is, and "if I add more lines it does not load more" means. Does the code not load on the arduino, or does the page not load in a browser? Perhaps you can put your web page html in a code box so it can be seen for evaluation.

They told me, it has a limit of sending packages by html. I should shorten the code and send it in smaller packages. the code compiles but does not load the web page as it is. In don't know how to short packages
