POST truncated at 8192 bytes

Tom Grahame
I'm facing a major problem where my POST operations are consistently truncated at 8192 bytes.

I don't think this is an Orbeon issue, but I wanted to ask if there might be anything missing on my submission element which could have an effect:

<xforms:submission id="submit" method="post" ref="instance('foxml')/foxml:digitalObject" replace="instance" resource="http://127.0.0.1/orbeon/addPublication.do" instance="submission-response">
        <xforms:send ev:event="xforms-submit-done" submission="checkSubmission"/>
</xforms:submission>

I'm on Orbeon Forms dev-3.7.1.200904170159, Tomcat 5.5.26, Solaris 10. I've also configured Apache2 as a front end using mod_rewrite (ajp) but it seems to also happen when I hit tomcat directly on port 8080.

Some googling says this might be a bug in this version of Tomcat, but it is difficult to tell.

Any advice is greatly appreciated.

Thanks,

Tom

Tom, did you try using different browsers?

Re: POST truncated at 8192 bytes

Yes - sorry I should have mentioned that.

The problem is consistent across Firefox 3.0.10, IE 6 and Opera 9.62.

I don't think it is a browser issue though, as I believe the POST is happening from the server to the server, although I could be wrong about that.

This most likely won't be caused by an issue with a browser, because  
the submission is done from the server. I'd recommend you use a tool  
like Wireshark or HTTPScoop (if you're on a Mac) to see what is going  
on between Orbeon Forms and the server you are calling.

Quick update -

I upgraded our Tomcat from 5.5.26 to 5.5.27 and I can now POST request bodies of >8192k.

Official Tomcat bug report -
https://issues.apache.org/bugzilla/show_bug.cgi?id=44494

That caused me some grief. Phew.

Thanks for your support Alex.

Best,

Tom

This is interesting; I didn't know about that limitation in pre-5.5.27 version of Tomcat. Thank you for sharing this!
