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.
By default, the post request has maximum size of 8mb. But you can modify it according to your requirements. The modification can be done by opening php.ini file (php configuration setting).
Find
post_max_size=8M //for me, that was on line:771
replace 8 according to your requirements.
