public OCSPRespondersCache(long maxTtl,
                           java.io.File diskPath,
                           java.lang.String prefix)
```
    Parameters:
    
    maxTtl - maximum time after each cached response expires. Negative for no cache at all, 0 for no limit (i.e. caching time will be only controlled by the OCSP response validity period). In ms.
    
    diskPath - if not null, cached responses will be stored on disk.
    
    prefix - used if disk cache is enabled, as a common prefix for all files created in the cache directory.
