Usage

From source file:Main.java

/**
 * Parse a deliminated string with keys and values like Content-Type parameters
 * and cache-control headers.  Keys can be present on their own e.g.
 * no-cache in which case the no-cache key will be in the hashtable with a
 * blank string value.  It can also have an = sign with quoted or unquoted
 * text e.g. maxage=600 or maxage="600"//  w w  w . ja  v a2s.  c om
 * 
 * @param str String to parse
 * @param deliminator deliminator character 
 * @return Hashtable of parameters and values found
