Subject: Rearrange placement of JSP limter code in JSP
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=acc3d9556fbbc83d8f7dbd818abf9cdcb34a4046;p=tomcat7.0

Rearrange placement of JSP limter code in JSP
servlet wrapper. Do everything in one place:

- add to the queue if this is the first time
  and only then check for the size and shrink
  if necessary

- move to the front of the queue otherwise

Move this in front of the actual servlet service.
