Is there a limit to the amount of data that can be submitted in a form?

All,

I haven't been around EE for a while, but knew this would be the place to get an answer.

Is there a limit to the amount of data that can be POSTed via a form in a web page?  Is it based on number of fields?  Number of bytes (say a textarea with a boatload of text)?  What?

The question really may be related to HTTP, but I didn't find an area for that.

Thanks in advance.

There is not a fixed limit per se, it depends on server settings.   <24k is usually safe, but I have done some PHP with up to 32meg posts.  Its usually not practical to pass anything too large via this method though....

... and don't forget file attachements.

So it's a webserver setting then?  OK.

Regarding file attachments, are you suggesting that as an alternative for uploading large amounts of data?

no, just meant that file attachements (pictures, movied, PDF or other documents) can take a lot of space...
... and the POST method can include file attachements (html tag: <input type="file">).

KeirGordon -- Do you happen to know where this setting can be found in IIS?
