What is the size limit of a post request?

Question

Sorry if this is duplicate,I would think it would be but couldn\'t find anything.

I have a flex application that I am posting data back to a php/mysql server via IE.

Answer 1

As David pointed out, I would go with KB in most cases.

php_value post_max_size 2K

Note: my form is simple, just a few text boxes, not long text.

(PHP shorthand for KB is K, as outlined here.)
