## General recommendations

* Use [HTTPS](https://en.wikipedia.org/wiki/HTTPS) (`https://...`) over [HTTP](https://en.wikipedia.org/wiki/HTTPS) (`http://...`) whenever possible

## Test a site before building a bridge

Some sites make use of anti-bot mechanisms (e.g.: by using JavaScript) in which case they work fine in regular browsers, but not in the PHP environment. To check if a site works with RSS-Bridge, create a new bridge using the [template](../05_Bridge_API/02_BridgeAbstract.md#template) and load a valid URL (not the base URL!).

**Example (using github.com)**

```PHP
<?php
class TestBridge extends BridgeAbstract {
	const NAME = 'Unnamed bridge';
	const URI = '';
	const DESCRIPTION = 'No description provided';
	const MAINTAINER = 'No maintainer';
	const PARAMETERS = array();
	const CACHE_TIMEOUT = 3600;

	public function collectData(){
		$html = getSimpleHTMLDOM('https://github.com/rss-bridge/rss-bridge')
			or returnServerError('No contents received!');
	}
}
```

This bridge should return an empty page (HTML format)
