I changed a bit of my code, and now I am starting the function with 900 free blocks.
I looked how much memory the function is using with E.getSizeOf() and got this:
```
>E.getSizeOf(sendMainPage, 1)
=[
  {
    name: "\xFFa",
    size: 1 },
  {
    name: "\xFFcod",
    size: 323 },
  {
    name: "\xFFlin",
    size: 1 }
 ]
>E.getSizeOf(sendMainPage)
=326
//326 Blocks * 16 =  5216 bytes
> 
```
So the function is using 20% from the total blocks (1600) or 36.2% from all available blocks (900) of the ram without the CSS.
But that's only the size when I request the page its using 430 blocks:
```
//start of the function sendMainPage
{ "free": 895, "usage": 705, "total": 1600, "history": 85,
  "gc": 0, "gctime": 1.827, "blocksize": 16 }
//after res.end();
467
>900-470
=430 //blocks
```
That's 47.7% of the free ram without CSS.
I think I got something that could help (How to send a large amount of data faster ?). But I don't know how that should work with the long HTML string. It would be nice if you could help me with this.

post # 'What do you mean with this?' ref: 'the 515 'usage' value'

See 'usage' below heading 'Description'

http://www.espruino.com/Reference#l_process_memory

My intent was to make aware the amount of memory used by the actual code instructions initially uploaded. As no source code had been provided before that #5 post, I had no way of knowing whether additional code was being uploaded from the Left-Hand console side of the WebIDE.

LAW of Unintended Consequences

post #1 'I have a simple http server that responds with an 8KByte website'

I mis-understood what task was being attempted while comparing your thread 'Is there a way to make a Basic Auth with the Webserver?' with this thread.

See sample snippet below example function getPage()

http://www.espruino.com/WiFi#using-wifi

As in that example, I took that phrase to mean a Http Request whose fetched content responds with 8K and memory became full during reception. And as there was no objection to the addition of FRAM in post #2, continued down that line of thinking.

A wild guess for post #6 last code block after heading 'This happens:' L3 might be that there is a missing trailing quote, mis-matched internal quote(s), improper nesting of quotes, missing semi-colon, etc.

Has the use of a Html validator been tried?

The use of base64 as @allObjects points out would assist in reducing those types of errors, but at the penalty of ~30% increase in string size.

Try reorganizing memory:
