-----------------------------------------

Hi James,

thanks for your POC, csrf is an important security topic when authentification is based on cookie!

Here are few questions/observations:
 * why did you choose csrfguard ? and how did you choose configuration (token length of 32 and algorithm SHA1PRNG)?
 * why do you add a map into session? tokenMap is a mapping to empty string, maybe it is better to use a Set in this case ? But actually multiple tokens in session at one time seems to me a mistake. I think that if we have multiple forms on one page it's enough to reuse the same token. Because if a user asks a page with a form but never submits this form, then asks another page with another form and again never submits this second form, we will end up with an ever growing tokenMap

> CRSF tokens are generated using CSRF Guard library and used in:
> 1) In widget form where a hidden token field is auto-generated.
> 2) In FTL form where a <@csrfTokenField> macro is used to generate the csrf token field.
> 3) In Ajax call where a <@csrfTokenAjax> macro is used to assign csrf token to X-CSRF-Token in request header.
> CSRF tokens are stored in the user sessions, and verified during POST request.
> A new attribute i.e. csrf-token is added to the security tag to exempt CSRF token check.
> Certain request path, like LookupPartyName, can be exempt from CSRF token check during Ajax POST call.
