Is there a limit with forms POSTing?

[Randell D.]

Folks,

Sorry for the cross post into multiple newsgroups on this, but html
forms processing is supported across all three groups so I was hoping
someone might know.

I did a check with Google and found dated 1996 and 1997... This is a bit
too old for me to rely on...

Thus... Does anyone know if there is a limit when POSTing? I think a
FORM METHOD of GET has a standards limit of 1024 though most browsers
ignore this limit... However I can't recall a limit when posting data.

Thanks... Replies please via the newsgroup so all can learn...

Servers can be configured to have limits on http posts. But they vary
from server to server. Typically it's quite a bit more than get though.

Because of the variable limits you might be better off using session vars
for storing info.

No official limit, although you the server will probably impose limits on
the size it is willing to accept. Both Apache and IIS have configuration
parameters which can be used to limit the maximum size of a request.

It is a good idea to set a maximum size on your server to prevent DoS
attacks attempting to upload multi-gigabyte files (unless you actually need
to upload very large files!)

See:

http://httpd.apache.org/docs/mod/core.html#limitrequestbody

for relevant Apache directives on maximum request size and also limits on
the number and size of fields.

Neither POST nor GET is limited by the spec, but there are
implementation-specific limits for both.

Theoretically, there's no limit, but I most definitely encountered a
limit at my shop. And it wasn't even that large of a limit, it
surprised me. I forget the numbers though. I guess this limit is
necessary to discourage hackers.

You've made an incorrect assumption... I'm not storing info - I'm
posting what could be a rather large <TEXTAREA> value - a few thousand
characters... perhaps (but unlikely) to hit the hundred thousand
characters... Its a one way transaction...

Thanks for replying...

Thanks - its my own server - its also an intranet based application -
Another ng reply tells me that there is a parameter that one can use
within Apache to create this limit - I will probably use it,but
configure it within my guesstimated limits...

thanks for the reply
