```
public interface ScalabilitySupportFactory
```
A host application can provide an instance of this interface that provides configuration and also create instances of ScalabilitySupport

Method Summary

- Method Detail
  - getInitialBufferSize
```
int getInitialBufferSize()
```
    Returns:
    
    the initial amount of memory to allocate to the SiteMesh buffer. This should be the sweet spot of average page size to prevent excessive re-allocation.
  - getMaximumOutputLength
```
long getMaximumOutputLength()
```
    Returns:
    
    the maximum output that SiteMesh will produce. If this is 0 or less then no maximum is in play
  - getMaximumOutputExceededHttpCode
```
int getMaximumOutputExceededHttpCode()
```
    Returns:
    
    the HTTP code to return if the maximum output is exceeded
  - isMaxOutputLengthExceededThrown
```
boolean isMaxOutputLengthExceededThrown()
```
    Returns:
    
    if this is true then the code will throw a MaxOutputLengthExceeded if the maximum output length is exceeded instead of sending back getMaximumOutputExceededHttpCode()
  - getSecondaryStorageLimit
```
long getSecondaryStorageLimit()
```
    Returns:
    
    the number of bytes to keep in memory before secondary storage is usd. If this is 0 or below then no secondary storage will be used
  - hasCustomSecondaryStorage
```
boolean hasCustomSecondaryStorage()
```
    Returns:
    
    if this produces a custom SecondaryStorage object
  - getSecondaryStorage
```
SecondaryStorage getSecondaryStorage(javax.servlet.http.HttpServletRequest httpServletRequest)
```
    If hasCustomSecondaryStorage() returns true, then this method will be called to get a custom implementation of SecondaryStorage from the host application. This method will be invoked for every request if used.
    
    Returns:
    
    a custom secondary storage implementation
