WebLink/ASP.NET Error

WebLink

Updated December 18, 2015

asked on August 14, 2014

I've got an in-house web application that generates a PDF and uses RA to create a document and attach the PDF as an electronic document. Then it takes the EntryID from that document and builds a WebLink URL and opens that in a new tab. The problem is that many times WebLink will show the following error:

If I manually browse to the document in WebLink it works just fine. In fact, if I take a browser window that's currently looking like the above screenshot and refresh it after I've manually touched the document, it starts working as well.

The error is actually an ASP.NET error that occurs when an application tries to specify a relative path that is above the root of the application.

This instance of WebLink is 8.2.1.

Have a look at this answer to see if it doesn't resolve your issue

https://answers.laserfiche.com/questions/59028/Weblink8-Browsingaspx-Error--CANNOT-OPEN-ELECTRONIC-DOCUMENTS

you may need to change the link to the following in order for this to work if the above answer does not:

https://xxxxxxxx/weblink8/ElectronicFile.aspx?docid=483610&dbid=0

I have a suspicion that it's due to the Intelligencia URL Rewriter that Laserfiche WebLink uses along with coding issues in WebLink. Classic Mode works directly with ISAPI extensions while Integrated Mode works directly and is tightly integrated with the ASP.NET request pipeline.

For example this URL will not be processed by the URL rewriter:

"https://xxxxxxxx/weblink8/ElectronicFile.aspx?docid=483610&dbid=0"

but the one you were having troubles with is processed by it.

By the way, is this WebLink installation running on IIS 7 or above?

It's on 7.5. Any other issues with running Classic mode? I'm not inclined to move my primary WebLink instance over when it's working just fine as it is. It's probably safer just to use the URL sample you've posted.

Thanks!

I personally have not seen any performance issues when switching to classic mode.

If anyone else comes across the "Cannot use a leading .. to exit above the top directory" error when using the REST-style URL, the problem was identified in SCR:77939 and fixed in Hotfix 1013039.

It has been rolled into 8.2.2 and 9.x releases.
