512k limit ?

[Philippe Chantry <ph...@inp-toulouse.fr>]

Hi all,

I'm trying to upload files to an ECM with a multipart POST HTTP request 
using HttpURLConnection.

It works fine if the file size is less than or equal to 524288 bytes (= 
512k), and fails if the file is larger.

Is 512k an inner limitation of groovy for a POST parameter size ? Is 
there some workarounds ?

(The same program written in pure java has not this limitation problem.)

Thank you,
Philippe

Hi Edinson,

Indeed, it was not a Groovy problem !

Thanks for your answer.

Hi there,

It should be notice that `HttpURLConnection` comes from Java and not from
Groovy.

After a quick Google search I got:

"HttpURLConnection does support the POST method, try
setRequestMethod("POST"). Also persistent connections are supported. Note
that the connection is only re-used after you have read the response body.
In the code example you posted it doesn't look like you are reading the
response. Since jdk6 the HTTP protocol handler will attempt to read-ahead
to make the connection available for re-use. It reads to up ~512k so if the
HTTP server returns megabytes of data and you aren't reading it then the
connection will be closed and not re-used." [1]

"HttpURLConnection
<http://download.oracle.com/javase/6/docs/api/java/net/HttpURLConnection.html>
*will* reuse connections if it can
<http://download.oracle.com/javase/6/docs/technotes/guides/net/http-keepalive.html>
!

For this to work, several preconditions need to be fulfilled, mostly on the
server side. Those preconditions are described in the article linked to
above." [2]
