查询字符串似乎会影响页面加载速度

Question

I'm working on this . It's hosted on c9.io, a browser based collaborative programming IDE

I have an index.php with a small script:

<?php
    $path = ltrim($_SERVER['REQUEST_URI'], '/');
    $elements = explode('/', $path);
    if(is_numeric($elements[0])){
        require_once 'post.php';
    }elseif($elements[0]==''){
        require_once 'main.php';
    }else{
        require_once '404.php';
    }
?>

When there is nothing in the url (only https://dickbutt-etaoin.c9.io ) it displays the page pretty much instantly but keeps loading for another five seconds during which none of the javascript on the page works

When I have a few numbers (for instance https://dickbutt-etaoin.c9.io/241 ) it's about as fast as it gets.

How can I make both the pages load at a normal speed?

I've tried reversing the order of if statements and it doesn't change a thing. Both the pages are relatively big, contain both php and javascript and a giant css file.

Answer 1

After some prodding in the network tab and googling, I found my answer.

I added this line of code to index.php

header('Connection: close');

Now it does what I wanted it to do. Thank you all for trying to help!
