when using the built-in method sendRedirect(url) you're limited to HTTP-GET requests and their associated limitations. Usually webservers and java application servers have configurable limits for the maximum URL length, which includes the URL parameters => hence the message (Request header is too large)

Technically it doesn't sound like there's a limit so if your configuration can be savely adapted to what you need, then you might be set with just a few configuration changes.

If changing the server limits is not an option, you already looked into the right direction using HTTP-POST (which allows larger parameters by default - since they are sent in the request body instead of the header).

Instead you need to create a native html form with e.g. (hidden parameters) and post it via javascript in the browser.

here a similar question maybe it already points you in the right direction: https://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit

However POSTing the request from the server won't/can't update the client side browser.
