<!-- The "controller" element describes the ControllerConfig bean     [org.apache.struts.config.ControllerConfig] that encapsulates     a module's runtime configuration. The following     attributes are defined:     bufferSize      The size of the input buffer used when processing                     file uploads.                     [4096]     className       Fully qualified Java class name of the                     ControllerConfig subclass for this controller object.                     If specified, the object must be a subclass of the                     default class.                     ["org.apache.struts.config.ControllerConfig"]     contentType     Default content type (and optional character encoding) to                     be set on each response. May be overridden by the Action,                     JSP, or other resource to which the request is forwarded.                     ["text/html"]     debug           Debugging detail level for this module. [0]                     DEPRECATED - configure the logging detail level                     in your underlying logging implementation.     forwardPattern  Replacement pattern defining how the "path" attribute of a                     <forward> element is mapped to a context-relative URL when                     it starts with a slash (and when the contextRelative                     property is false). This value may consist of any                     combination of the following:                     - "$M" - Replaced by the module prefix of this module                     - "$P" - Replaced by the "path" attribute of the  selected                     "forward" element                     - "$$" - Causes a literal dollar sign to be rendered                     - "$x" - (Where "x" is any character not defined above)                     Silently swallowed, reserved for future use                     If not specified, the default forwardPattern is "$M$P",                     which is consistent with the previous behavior of                     forwards.  Since Struts 1.1.  ["$M$P"]     inputForward    Set to "true" if you want the "input" attribute of                     <action> elements to be the name of a local or global                     ActionForward, which will then be used to calculate the                     ultimate URL. Set to "false" (the default) to treat the                     "input" parameter of <action> elements as a                     module-relative path to the resource                     to be used as the input form. Since Struts 1.1.                     [false]     locale          Set to "true" if you want a Locale object stored in the                     user's session if not already present.                     [true]     maxFileSize     The maximum size (in bytes) of a file to be accepted as a                     file upload.  Can be expressed as a number followed by a                     "K", "M", or "G", which are interpreted to mean kilobytes,                     megabytes, or gigabytes, respectively.                     ["250M"]     memFileSize     The maximum size (in bytes) of a file whose contents will                     be retained in memory after uploading. Files larger than                     this threshold will be written to some alternative storage                     medium, typically a hard disk. Can be expressed as a number                     followed by a "K", "M", or "G", which are interpreted to                     mean kilobytes, megabytes, or gigabytes, respectively.

["org.apache.struts.upload.CommonsMultipartRequestHandler"]     nocache         Set to "true" if you want the controller to add HTTP                     headers for defeating caching to every response from                     this module.  [false]     pagePattern     Replacement pattern defining how the "page" attribute of                     custom tags using it is mapped to a context-relative URL                     of the corresponding resource.  This value may consist of                     any combination of the following:                     - "$M" - Replaced by the module prefix of this module                     - "$P" - Replaced by the value of the "page" attribute                     - "$$" - Causes a literal dollar sign to be rendered                     - "$x" - (Where "x" is any character not defined above)                              Silently swallowed, reserved for future use                     If not specified, the default forwardPattern is                     "$M$P", which is consistent with previous hard coded                     behavior of URL evaluation for "page" attributes.
