Subject [jira] Commented: (HTTPCORE-79) DateUtils should cache SimpleDateFormat
Date Sun, 17 Jun 2007 15:09:26 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-79?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12505597
] 

Roland Weber commented on HTTPCORE-79:
--------------------------------------

I've taken a look at FastDateFormat. It maintains several internal caches in form of static
HashMaps.
I'd hate to introduce that as a default anywhere in HttpComponents.

Moving DateUtils to HttpClient/Cookie sounds good. There we can take as many stabs at it as
we want to.

cheers,
  Roland

> DateUtils create a SimpleDateFormat for each invocation of #formatDate and #parseDate.
This can be optimized if SimpleDateFormat instances are cached. Since SimpleDateFormat is
not threadsafe, the cache must be threadlocal.
