Paul King commented on GROOVY-1200:
-----------------------------------
This issue is quite old. Before commencing, it would be worth doing a gap
analysis between what is currently available[1] and what might be expected
within vanilla JSP code[2].

> include appropriate JSP 2.0/EL implicit variables in Groovlets

> Key: GROOVY-1200
> URL: https://issues.apache.org/jira/browse/GROOVY-1200
> Project: Groovy
> Issue Type: New Feature
> Components: Groovlet / GSP
> Affects Versions: 1.0-JSR-4
> Reporter: Demis Bellot
> Labels: contrib
>
> While we're making life easier for the developer we should also add familiar
> JSP 2.0/el objects where appropriate.
> looking at: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSPIntro7.html, we
> see these variables
> * param: Maps a request parameter name to a single value
> * paramValues: Maps a request parameter name to an array of values
> * header: Maps a request header name to a single value
> * headerValues: Maps a request header name to an array of values
> * cookie: Maps a cookie name to a single cookie
> * initParam: Maps a context initialization parameter name to a single
> value
> Finally, there are objects that allow access to the various scoped variables
> described in Using Scope Objects.
> * pageScope: Maps page-scoped variable names to their values
> * requestScope: Maps request-scoped variable names to their values
> * sessionScope: Maps session-scoped variable names to their values
> * applicationScope: Maps application-scoped variable names to their values
> Out of these i think it makes sense to have:
> param,paramValues,header,headerValues,cookie,requestScope,sessionScope,applicationScope
