What is the recommended way to pass urls as url parameters?

Question

Using `&url='+encodeURIComponent(url);` to pass a URL from browser to server will encode the url but when it is decoded at the server, the parameters of url are interpreted as seperate parameters and not as part of the single url parameter. What is the recommended way to pass urls as url parameters ?

Accepted Answer

`encodeURIComponent()` should work. For example,

```
'&url=' + encodeURIComponent("http://a.com/?q=query&n=10")
```

produces

```
"&url=http%3A%2F%2Fa.com%2F%3Fq%3Dquery%26n%3D10"
```

(which doesn't have any `&` or `?` in the value). When your server gets this url, it should be able to decode that to get the original:

```
param["url"] = "http://a.com/?q=query&n=10"
```

I'm not sure what server you're using (e.g. Rails, Django, ...) but that should work "out of the box" on any normal system.
