appendHashSuffix

public static String appendHashSuffix(String url,
                                      String hash)

Appends a suffix containing the hash code, if given. The file name is repeated to satisfy browsers with the correct type and file name, though it is not used by the servlet.

Parameters:

url - an url to which we append the suffix

hash - optional, the hash code

Returns:

the url with suffix /{hash}/{filename} appended, where {filename} is the last part of a / separated url.

parseHashFromSuffix

public static String parseHashFromSuffix(String suffix)

Does the inverse to appendHashSuffix(String, String): extracts the hash from the generated suffix.

Parameters:

suffix - the suffix generated by appendHashSuffix(String, String) , nullable

Returns:

the hash if it could be extracted, otherwise null.
