[S2] Can an interceptor save the request to use it later ?

[Andrea Vettori]

Hi,

I have a login interceptor that checks the presence of a token in the  
session. If the token is not present it returns LOGIN; if present it  
invokes the action. LOGIN is a global result that calls the login  
action.

What I want to do is: after the login is completed the system should  
process the original request with all the parameters.

I already can do this composing the request URL getting the action  
name, context, parameters name and values from ActionInvocation in the  
interceptor and storing it in a session variable and after the login  
redirect to that URL.

What I want to know is if it exists a better way to do this, for  
example saving the ActionInvocation object insted of composing the URL  
and then use that to execute the original action in the interceptor.



Something like this :


public String intercept (ActionInvocation ai) {

        if (session contains saved invocation)
                continue that invocation and clear session saved invocation
        else {
                if (session contains token)
                        ai.invoke()
                else
                        return LOGIN
        }
}



I dont' like using the "composed URL method" even if it works, because  
it has some "hardcoded" values (i.e. the .action suffix) and because  
it converts all parameters to strings and then back to their original  
variables type when the URL is used in the redirect.


Thanks
