WebServer Issue loading pages and commands not working

Hi to everyone,
I've got a problem with my actual project (I'm new about programming and arduino),
my hardware setup is : Arduino Nano, ethernet shield ENC28J60 (for Nano).
The problem is that i'm new about this programming world and i don't have enough knowledge about TCP and HTTP comunication. However in my actual project i've to create a webserver with two pages that controls a network configuration and the other page have to control 6 relays. The two programs works when are separated, but i've got a lot of bugs and loading problems when I combine them together.
I think that the problem is correlated with the TCP connection or HTTP requests.
Here is the code, i hope someone can help me:

#include <UIPEthernet.h>
#include <TextFinder.h>
#include <SPI.h>
#include <EEPROM.h>
#include <avr/pgmspace.h>
//PIN definition 
#define RESET 9 //pin per reset manuale
const byte INDEX = 4;  //Array dimension (ip, mask, gw, dns)
const byte RELE_NUM = 6;
const PROGMEM byte rele_pin[RELE_NUM] = {2, 3, 8, 5, 6, 7};

//Reset states
int lastState = LOW;  // the previous state from the input pin
int currentState = digitalRead(RESET);
//Default Network Settings
const PROGMEM byte default_mac[RELE_NUM] = { 0x00,0x01,0x02,0x03,0x04,0x05 };
const PROGMEM byte default_ip[INDEX] = { 192,168,65,250 };
const PROGMEM byte default_subnet[INDEX] = { 255,255,255,0 };
const PROGMEM byte default_gateway[INDEX] = { 192,168,65,254 };

//Start Network Settings
byte mac[RELE_NUM] = { 0x00,0x01,0x02,0x03,0x04,0x05 };
byte ip[INDEX] = {192,168,65,250};
byte subnet[INDEX] = {255,255,255,0};

You need to describe those bugs and problems in detail in order for us to help you. For each bug/problem, describe what actually happens and what you wanted or expected to happen.

I see a lot of code duplicates where only minor things are changed line by line. That makes reading your code very ....

I propose you get rid of it and use more functions where you hand over the changing parts with parameters.
Furthermore, your http request doesn't contain a content length, so it is only 1.0.
Don't use the F-Makro with client.print, it will have negative effect on the performance of your webserver (and a very long communication time to your webbrowser).
I can recommend the streamlib from Juraj or - as you are already using a temporary buffer - use the buffer more consequently.

You can get more information on that topic on my page:

Ok, so when the program is running i search in the browser my ip adress: (to reach the setting page) and the page loads two or three times (i'll show you the serial monitor), then the page works fine it seems, but when i click to the topnav link to switch page, i've to click it a few times to reach the "commands page" and the page loading never ends, however in the serial monitor i see that the "settings page" is reloaded. I would to keep a stable connection and I'd like to make commands work, because when i click to one button nothing happends.
P.S. sorry for my bad english.


this is what the Serial monitor tells me when i reach the first page (* Settings *), it should be load only once.


this is what's happen when i click to switch to the other page ((* Commands *), it reload the client and it tells me (settings) but when i click on it a few times finally i can reach the commands page. When i'm inside the other page the loading never stop, and if i try to click on one button (>>>Commands) nothing actually happens. It should tell me something like ( R1_PLAY ) when i cick to "play button".

@noiasca UIPEthernet doesn't send single bytes over network as Ethernet. (but does sent them as single bytes over SPI)

maybe try the EthernetWebServer library.
and EthernetENC library is usually better then UIPEthernet

Thanks for the advices but i only want to know how can i how can I make the two web pages coexist in the same function "web_page(void)".
For many reasons i can't change my libraries, one of those is that i've to send the project in a few days and i'm so scared, i hope someone can help
