Anyone know the max size limit of the HTTP header?..

i.e. how much data can be put into the header from a form on a website to be parsed by php and stored in a MYSQL DB..

Is there a work around for it to transfer?..

Data from a form post isn't sent in the response header - it's sent as MIME-encoded body data. The only thing that goes in the header is Content-Length and a few things like that.

If the form is POSTed, then Travis is correct, there is no (practical) limit. If the form is GETed, then the form data is sent as part of the query line; there is no theoretical limit to this, but most HTTP servers will refuse a request if the query line is more than a couple KB. I think up to 512 bytes is always safe, though.

Basically, if you have to ask, you should probably stick to POSTing your data.

thanks.
