@IncompatibleChange(release="5.4",
                    details="resource parameter added, IOException may now be thrown")
String constructAssetPath(String virtualFolder,
                          String path,
                          StreamableResource resource)
                   throws IOException
```
    Constructs an asset URL path from the virtual folder and path (within the virtual folder). After constructing the string (and honoring the SymbolConstants.ASSET_URL_FULL_QUALIFIED symbol), the result is passed through the AssetPathConverter.
    
    Parameters:
    
    virtualFolder - corresponds to a AssetRequestHandler contributed to the AssetDispatcher service
    
    path - a path that can be used to identify the underlying Resource or or re-acquire the StreamableResource; this will be the final portion of the URL, after the appropriate prefix (based on whether the resource is compressed or not) and the checksum for the resource
    
    resource - underlying resource for the asset path; the checksum portion of the URL is obtained from the resource
    
    Returns:
    
    path portion of asset URL, which is everything needed by the AssetDispatcher to find and stream the resource
    
    Throws:
    
    IOException
