title: absLangURL
description: Returns an absolute URL with a language prefix, if any.

keywords: [urls, multilingual,i18n]
signature: ["absLangURL INPUT"]

Use this function with both monolingual and multilingual configurations. The URL returned by this function depends on:
- Whether the input begins with a slash
- The `baseURL` in site configuration
- The language prefix, if any
In examples that follow, the project is multilingual with content in both Español (`es`) and English (`en`). The default language is Español. The returned values are from the English site.
### Input does not begin with a slash
If the input does not begin with a slash, the resulting URL will be correct regardless of the `baseURL`.
With `baseURL = https://example.org/`
```go-html-template
{{ absLangURL "" }} → https://example.org/en/
{{ absLangURL "articles" }} → https://example.org/en/articles
{{ absLangURL "style.css" }} → https://example.org/en/style.css
```
With `baseURL = https://example.org/docs/`
```go-html-template
{{ absLangURL "" }} → https://example.org/docs/en/
{{ absLangURL "articles" }} → https://example.org/docs/en/articles
{{ absLangURL "style.css" }} → https://example.org/docs/en/style.css
```
### Input begins with a slash
If the input begins with a slash, the resulting URL will be incorrect when the `baseURL` includes a subdirectory. With a leading slash, the function returns a URL relative to the protocol+host section of the `baseURL`.
With `baseURL = https://example.org/`
```go-html-template
{{ absLangURL "/" }} → https://example.org/en/
{{ absLangURL "/articles" }} → https://example.org/en/articles
{{ absLangURL "/style.css" }} → https://example.org/en/style.css
```
With `baseURL = https://example.org/docs/`
```go-html-template
{{ absLangURL "/" }} → https://example.org/en/
{{ absLangURL "/articles" }} → https://example.org/en/articles
{{ absLangURL "/style.css" }} → https://example.org/en/style.css
```
{{% note %}}
The last three examples are not desirable in most situations. As a best practice, never include a leading slash when using this function.
