POST size ?

[WJ]

I use POST method to send a payload of three "Name,Value" pairs to an aspx
page. The 2nd pair with a value of a string type and is 700 bytes long.
However, the string is truncated to 360 bytes (approx.) by the time it
reaches the destination page.

I thought POST would cary a higher payload. What is the maximum size of a
"name,value" pair can a POST absorb ?

Thanks

I don't know the Maximum size of a post you have to take a look at the HTTP
specs for that on www.w3c.org

You should try setting the ContentLength of your HTTP POST to 700

This can be configured using the urlscan.ini file if you're using
urlscan with IIS (and you should be).

This file says the default length of the query string is 2048. This
probably varies with each IIS version. The above value came from
version 5.1 (Windows 2000 server)

There's no limit. Maybe the specified Content-Length header is smaller
than the actual payload's size. Can you post some code?

Thank you all for your response. Unfortunately, the "content-length" is not
the culprit. In my string value, whenever there was a double-quotes ("), the
string was truncated at that point. I changed the double quotes to a single
quote and it accepts as large a string as it could.
