Using SWFUpload, why are my uploads not being proceesed by upload.aspx when using Firefox (they are processed correctly in IE)?

Answer 1

Good chance that since this is working in IE and not in Firefox and you are trying to do some authentication ( hence post_params: { "ASPSESSID": "<%=Session.SessionID %>" },) you are hitting the flash/firefox/opera "bug"/issue. In this case the flash uploader is actually running in its own context and not in the shared context and can not acess the cookies for the sessionID.

Use a debugger to check and see what is being generated or if you have an error there.

There are several threads in the forum here, I think some for ASP ( not my specialty) that give some workarounds. Search for flash, upload, sessionId and ( ASP)

The code looks o.k. to me.

• Does the Firefox console show any errors?

• Can you try using paths relative to the web root /xyz/swfupload/upload.aspx to make sure it's not a case of relative paths being resolved differently?

• Are you 1000% sure your aspx file is actually not being called? Or could it be that just the authentication process goes wrong for some reason? Can you put a log or mail command into the 1st line of the ASPX file?

• Does the upload process itself start and show a progress bar?

• SWFUpload comes with error handler hooks. Do none of them throw an error message?
