Use hidden iframe to submit data

Question

I need to submit some information to my servlet. Once I submit this information, I\'ll receive a PDF from the servlet based on the data. I know I can construct the URL and pass

Hm, which way do you want to sent the data using your iframe? I think you're limited to either GET or POST there, too. Means, if your data is too large, the iframe won't help sending your data.

What server backend do you use? You might be able to configure the maximum size of request data (post / get).

Please have a look at this message for more information about this.
