Specific's on sending HTML over HTTP/TCP

Hi Everyone, Anyone know the specific's on the best way to send an HTML page using two espconn_send calls. Right now I have to doublebuffer to send the Data with the correct header. I would like to just send the header string without having to get it all into one huge buffer and spitting it out, The code below are examples of what I've tried to get it to work both using keep alive and using close to let the HTTP client know when I'm done sending the data be only to fail. Any thing I am missing?

Code:

LOCAL void ICACHE_FLASH_ATTR HttpSendWithHeader(struct espconn * WifiScanConfigConnection, unsigned char * LFormatedHTMLPage) 
{
   //os_printf("Attaching header and sending\r\n");
   os_memset(FormatedHTMLPageWithHttpHeader, 0, HTMLSIZE);
   os_sprintf(FormatedHTMLPageWithHttpHeader, "HTTP/1.1 200 OK\r\nContent-Length: %d\r\nConnection: close\r\n\r\n", os_strlen(LFormatedHTMLPage));
   os_strcat(FormatedHTMLPageWithHttpHeader, LFormatedHTMLPage);
   espconn_send(WifiScanConfigConnection, (uint8*)FormatedHTMLPageWithHttpHeader, os_strlen(FormatedHTMLPageWithHttpHeader));
   os_printf("HTTP Response sent bytes: %d\r\n", os_strlen(LFormatedHTMLPage));
}

vs.

Code:

LOCAL void ICACHE_FLASH_ATTR HttpSendWithHeader(struct espconn * WifiScanConfigConnection, unsigned char * LFormatedHTMLPage) 
{
   //os_printf("Attaching header and sending\r\n");
   os_memset(FormatedHTMLPageWithHttpHeader, 0, HTMLSIZE);
   os_sprintf(FormatedHTMLPageWithHttpHeader, "HTTP/1.1 200 OK\r\nContent-Length: %d\r\nConnection: keep-alive\r\n\r\n", os_strlen(LFormatedHTMLPage));
   //os_strcat(FormatedHTMLPageWithHttpHeader, LFormatedHTMLPage);
   espconn_set_keepalive(WifiScanConfigConnection, ESPCONN_KEEPCNT, NULL);
   espconn_send(WifiScanConfigConnection, (uint8*)FormatedHTMLPageWithHttpHeader, os_strlen(FormatedHTMLPageWithHttpHeader));
   os_printf("HTTP HEADER Response sent bytes: %d\r\n", os_strlen(FormatedHTMLPageWithHttpHeader));   
   espconn_send(WifiScanConfigConnection, (uint8*)LFormatedHTMLPage, os_strlen(LFormatedHTMLPage));
   os_printf("HTTP BODY Response sent bytes: %d\r\n", os_strlen(LFormatedHTMLPage));
   //espconn_disconnect(WifiScanConfigConnection);
}
