Remove one parameter from the query string

[Nalini Nagarathinam]

Hi,

I have a requirement, for that i need to remove the particular parameter from the query String.

Let say,

String s = request.queryString();

Ex, S value is "abc=site&test=test1&foo=value&test2=test2"

I want to remove the foo parameter from the above query string. Foo parameter can be at anywhere in the string(start, end of the string)

Shall i use regex to find the pattern or any other way to remove it in servlet?

For what purpose? The query string has already been submitted, what use is there in modifying it?

Hi,

Thank you for your reply

I want to remove one parameter and add a new parameter and post it as the POST request.
This is my requirement.

use replace method of string .

for example.

s.replace("foo", "");

Hi

Wht you have suggestted is fine for to replace the string foo.

But i need to replace the parameter foo=value.

My Solution:
1) we can write the pattern to find the string and replace
2) Use request.getParameterValues& getParameterNames to the parameters, loop through the parameters and remove it.

Thanks,

second one looks more appropriate.
