RE: Barracuda: CVS Update - Memory leak fix

Yep! Last week (12/6)...I probably forgot to announce it on the list,
although if you are subscribed to the Barracuda-commits list you would have
seen it there. Here are the details:
--------------------------
<b>csc_120602.2</b> - Bunch of minor formatting changes (ie. remove tabs
that
crept into the code, etc

<b>csc_120602.1</b> - Change HttpServletRequestWrapper so that
getParameterMap
returns map values as String[], like its supposed to according to the spec.
Also
make it handle multiple values (previously it didn't). Thanks to Udovenko
Sergey
[[email protected]] for bringing this to my attention.

<b>csc_120502.1</b> - Added support to BaseEvent class to support the notion
of
params. This means adding the following methods:
- void setParam(String key, String val)
- void setParam(String key, String[] vals)
- Map getParams()
You can use these events to "add" parameters to a URL request. Basically, if
you
shove any values in here, then when this event is dispatched (by adding it
to
the event queue) then the param values will get pulled out and appended into
the
underlying Http req object. Thus to the code that handles this event, it
will look
like the parameters where there all along. Pretty slick! Thanks to Jack
Hodges
