Make sure your server is sending the ```Connection:keep-alive``` header
## Using the test without PHP
If your server does not support PHP, or you're using something newer like Node.js, you can still use this test by replacing `garbage.php`, `empty.php` and `getIP.php` with equivalents.
If your server **does not support PHP**, maybe you have only **nginx** for static files, or you're using something newer like **Node.js**, you can still use this test by replacing `garbage.php`, `empty.php` and `getIP.php` with equivalents.
For **nginx** see comments below and [example 9](example9_no_backend.html#L115)

It is important here to turn off compression, and generate incompressible data.
A symlink to `/dev/urandom` is also ok.
**nginx**
Use tool above to generate static known file size. Upload to server so it is available something like `/speedtest/20MB.file`
#### Replacement for `empty.php`
Your replacement must simply respond with a HTTP code 200 and send nothing else. You may want to send additional headers to disable caching. The test assumes that Connection:keep-alive is sent by the server.
**nginx**
1. Increase allowed POST body size
2. Create empty text file `empty.file`
3. Allow HTTP POST method to static/empty file and return HTTP 200 even nothing is saved or processed by server
```nginx
location /speedtest/empty.file {
client_max_body_size 30M;
error_page 405 =200 $uri;
}
```
#### Replacement for `getIP.php`
Your replacement must simply respond with the client's IP as plaintext. Nothing fancy.
**nginx**
```nginx
location /speedtest/getip {
return 200 $remote_addr;
}
```
#### JS
You need to start the test with your replacements like this:
