MaxPostSize for XHR uploads

[Serge Droganov]

Hello,
We're using XHR image uploader for the app and faced a problem.
Files bigger than 20 MB are not accepted by the server.

We can handle same problem for post uploads with MaxPostSize tomcat
setting.

But I just have no idea how to manage XHR issues.

Could someone help me with that?

Do you have a cftimeout bypass on the pages?

No, what is cftimeout? Request timeout is not thrown...
I beleive this is Tomcat Problem

Serge.

This is weird cause an xhr call is 100% same as an http call for the server perspective.
Are you sure nothing in your code checks for file size ???

What error do you get ?

Hello Andrea. I get no error. File is zero KB on disk.
The same file can be uploaded with post request.

I use valums uploader.

Len(getHttpRequestData().content) is 0

May you create a test case?

Thanks

It looks like I'll have to :-)

Do you have any proxy servers in front of tomcat?

Nginx Apache? if so check max client body size parameters in those
proxy servers.
Nginx is client_max_body_size set to 100M or whatever your needs are

[Serge Droganov]

Yes, nginx has that setting. If it was nginx we wouldn't had zero
fileon the disc.It would be http error in that case.

Nope it returns 200 and valid json response.

if(NOT isImageFile(tmpFile)) {
throw("Файл «" & tmpFileName & "» не является изображением!");
}

I had the same issue with IIS7+Railo+JQuery Uploadify. Anything bigger
than 30MB or so to upload would fail. Just got to know that IIS7 has
a limit of 30MB (or rather 28.61MB) for uploading files by default.
After it's been changed, everything works perfectly.

[Serge Droganov]

Yes, we're building a testcase to check everything today. We don't use
IIS, and I also don't think that it is a front end problem. I got some
old opera it doesn't support XHR and script falls to iframe upload if
I use it. Opera is able to upload big files with post, and other
browsers don't with XHR.

[Andrea Campolonghi]

Serge.

Check the call you make in xhr. Something wrong must be there.
From the server side a classic post call and a post via xhr are absolutely the same thing.
You say that a file is written as 0 byte. So possible that file is not passed or parsed correctly.
Are you using some html5 fileuploader?

Andrea, I really don't think it is a script.
1. Upload takes time
2. Files below 40 MB are uploaded fine with XHR

I'll build a testcase soon, just too busy now to make experiments.
