34/// Retrieves and customizes the SDK content.
35///
36/// This function gets the SDK content based on the URL and customizes it for the given host and autocapture settings.
37/// For URLs ending in "sdk.js", it returns the latest version. Otherwise, it extracts and returns a specific version.
38///
39/// # Arguments
40///
41/// * `url` - A string slice containing the URL path to get the SDK from (e.g. "/_edgee/sdk.js" or "/_edgee/edgee.v1.5.0.js")
42/// * `host` - A string slice containing the host domain to customize the SDK for
43/// * `autocapture` - An Autocapture struct specifying which events to automatically capture
44/// * `edgee_cookie` - A string slice containing the name of the Edgee cookie
45///
46/// # Returns
47///
48/// * `Ok(String)` - The customized SDK content if successful
49/// * `Err(&'static str)` - An error message if the SDK content could not be retrieved
50///
51/// # Example
52///
53/// ```rust
54/// use edgee_sdk::Autocapture;
55/// let url = "/_edgee/edgee.v1.7.3.js";
56/// let host = "example.com";
57/// let sdk_content = edgee_sdk::get_sdk(url, host, Autocapture::default(), "edgee");
58/// assert!(sdk_content.is_ok());
