Hello Experts,
I am working on a project which uses ESP8266WebServer.h on my ESP8266 01 module (tried the same code with ESP8266 Nodemcu)
The issue I am facing with both the boards is when I load the page by visiting its IP address then complete HTML code is not loaded.
Understandably, there are mistakes in the code if the same part of the code is missing every time, But in my case, different parts are missed every time. Like sometimes the last lines are missing. Sometimes half of tag is missing, sometimes my CSS styling is missing & sometimes it is just blank 
My HTML code consists of the Concatenation of small-small parts which concats code with the Arduino variables. In the ESP8266 01 module the code never loads completely & in Nodemcu, sometimes the complete code is loaded.
My HTML code size is approx 8kb & I am storing the code in String as raw data.
String HTML = R"(<HTML> .........)" + someother data + R"(.........</HTML>)"
What do you think is wrong?
Should I use another library?
Or ESP8266 is insufficient for all this?
Please let me know what should I do with this.
Thanks & Regards!!
