forwardPattern Replacement pattern defining how the "path" attribute of a

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

"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",

inputForward Set to "true" if you want the "input" attribute of

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.

of the corresponding resource. This value may consist of
any combination of the following:
