Ecm ucf session wait timeout [dfc_acs_log_no_nl] Problem Analysis

Status:

When chrome executes the Webtop Upload File function of ECM, The UCF session wait timeout error is returned. However, it works normally in IE.

Upload is a customized function.

Solution Analysis:

1. suspected to be the cause of Java applet. Because chrome uses different JRE and IE.

Chrome cannot find the JRE installed on the system, unless the registry information is modified. Therefore, when you open a page containing an applet using chrome, you will be prompted to reinstall it.

Set the JRE of chrome and IE to the same, and find that there is still a problem.

2. decompilation tracking code. It is found that the problem occurs when sessionmanger obtains the session.

Comparison between IE and chrome.

When IE is used, sessionkey is included in m_unusedsessions.

But Chrome is not. So chrome will wait 60 s for the session, but the session time is out after 60 s.

Index = m_unusedsessions.indexof (sessionkey) =-1

3. Check the differences between IE and chrome on the page.

IE is to open a new page to upload files

Chrome operates on the same page.

It is hard to say that Chrome is on the same page. Is that session always in use?

Use Chrome to pop up a new page to solve this problem.

This setting can be achieved by modifying the relevant JS Code in wdk. js.

I have not tried the specific results ....
