Append key/value pair in URL java
We have a scenario in our mobile app where we want to add a parameter to the header or url so that the firewall can validate the request based on the parameter sent. Authentication needs to be done before it reaches the server. Is there anyway to append any information to url or request headers for the subsequent requests from the server.
I like to append name/value pairs to the URL's from within a servlet or action class so that based on the key value pair we can have a rule in firewall to validate the request.

all the jsp's use POST method.
You can use servlet instead of JSP

this is an existing application so I would not be able to change the architecture.
So what can you do?
Maybe you can change the action of the form direct it to intermediate servlet
which would modify the URL and then call your ultimate page
and in that itntermediate servlet uyou'll change as you want.

moreover GET would have size limit, the app might have many fields in the form.
Last I heard, Authentication is always done by the server.

This is not a complete solution, as we are not looking for GET requests.
I guess you don't understand then that "I like to append name/value pairs to the URL's" is by definition a GET request. You can not put or see POST requests in the URL.

Dave .. you can append parameters to POST requests explicitly like this
<form id="form1" name="form1" method="post" action="print?<%= session.getAttribute("auth
let me know if this is wrong
<form id="form1" name="form1" method="post" action="print?<%= session.getAttribute("auth
let me know if this is wrong
No, that is not 'wrong' but the server receives the part after the URL and '?' as a query string and puts that in the GET array, not the POST array. I have done exactly what you are talking about a number of times and you will Not find that info the POST array on the server. It will be in the GET array though sometimes (in PHP), you can retrieve it thru the REQUEST array which in PHP combines both POST and GET.
So when you submit a form as a POST with a query string, you are submitting both POST and GET information. Yes, you can do that (I have done that) but you have to know which is which so you know where to look for the different items in the program page that receives the info.

in the <form... > element then it will pass your parameters in
the URL itself
Yu can then use say hidden element(s) to pass any parameters you want in the URL
string to the next page
