Multiple Servers Upload

#1 Postby vzmind » Jun 21, 2007 10:18 am

Hi,

I am using XUpload Pro 2.5. Everyting is working fine .... as long as the upload form and the perl cgi are on the same domain. Let me explain more precisely.

Imagine Server www.front.com is your front web server and www.files.com is your files server. You have the form on www.front.com but the action called by it is someting like www.files.com/xupload.cgi. When you load the page it's ok. But when you start upload every second (maybe less) a javascript error is throw (uncaught exception: Permission refusée d'obtenir la propriété HTMLDocument.getElementById) until the end of upload. The progress bar dont move at all. At the end of file transfert, the progress bar go directly to 100% and you are dropped to your post_url.

My interpretation is that the xupload.js located on www.front.com cannot communicate with the xupload.cgi located on www.files.com. That's a security limitation of javascript.

Have you an idea on how I can go through?

Many thanks in advance, I have spend so much time on google and this forum to find a solution without result.

Vz :shock:

What upload mode do you use? Try pop-up or in-iframe modes.

Hi Pilgrim,

thanks for your reply. The fact is that our customer has some technical constraints and dont want to use such tricks. So, we have thought to put an additionnal perl CGI on front.com. In that way, files.com will first communicate with front.com through PERL and then ONLY push data to a LOCAL JS. But honnestly, we havent your PERL talents and it's must be a huge work.

Following, here is a part of our configuration file with the upload mode variables. In<FORM>, our enctype is "multipart/form-data".

Do you agree that it's not possible with actual application architecture to upload on different domain?
Have you some other technical tricks (dif of PopUp or IFrame) to help us?

Best Regards and thanks again for this work.

Erm....I guess you got me wrong. In upload form there are 4 radiobuttons, right. Each is progress bar mode. 1st is pop-up, 2nd and 3rd are iframe-in, 4th is on-page.
4th mode won't work with multiple domains, but 1,2,3 modes should work, at least they work for me with different domains(only Stop button doesn't work due to JS security).

That was on-page.So ok, if there are no technical solutions let's move to popup option.
Many thanks for your involvment and your support. :D
