Description:

The forward and include wrappers simulate servlet container dispatch operations by overriding path element getters and adding the appropriate request attributes. To properly implement these they need to adapt when a real dispatch is performed. When the servlet container performs a dispatch it doesn't add a wrapper at the front of the request chain, instead it changes the original request at the back of the chain (or inserts a wrapper inside the chain just after the original one). To detect this the Blossom wrappers probes the chain behind them to figure out if something has changed. They need to know this in order to decide whether they should override attributes and path elements.

While these calls are quick and simple they're called very frequently and need to be as fast as possible.

In BLOSSOM-130 a major improvement was made by letting the include wrapper switch itself off when a real include dispatch happens.

With this issue we should take the same approach for the forward wrapper. Other possible performance improvements should be investigated as well.
