Marketo tracked link to .aspx error

[Anonymous]

Hi all,

Is there a known issue with Marketo tracked links causing an error message when directed to a .aspx webpage?

The scenario is:

A Marketo email with two links, both  .aspx pages with Munchkin code, is sent. Link A has a Marketo form iframed on a .aspx page, Link B has no form but does have Munchkin tracking code on a .aspx webpage. Both pages are part of the same microsite. 

Link A (the page with the Marketo form) works fine with the Marketo tracking code.
Link B (the page with no form) gives the error message: error.aspx?aspxerrorpath

The same error message was given when additional links were tested with normal tracking enable directed to the same .aspx website.

All links work with the Marketo tracking disabled using class=MktoNoTrack, however it is important in this campaign to track clicks link in email to both measure engagement and cookie known leads. 

This community article suggested that a Marketo landing page used to redirect to the .aspx page would allow the clicks to be tracked and still land on the .aspx webpage: https://community.marketo.com/MarketoArticle?id=kA050000000Kyq2&src=comm

However, the link to the redirect page worked, but upon redirecting to the .aspx page the same error.aspx?aspxerrorpath message was given. This redirect worked fine when tested with Link A to the .aspx Contact page with the iframed Marketo form.

Does anyone have experience with linking to .aspx pages? I would like to know why this is causing an error message on all pages except the one with the iframed Marketo form, and how we can track clicks while still linking to these .aspx pages?

Thanks for your help!

Have you tried leaving off the ".aspx" extension from the URL?  The ".html" extension on Marketo landing page URLs is not required, and I've seen it cause problems if included.

Thanks for your suggestion Elliott! Unfortunately leaving off the .aspx returns a 404 - File or directory not found message.

Sounds like the issue is the tracking decoration on the link, somehow.  Can you post a decorated and an undecorated version of the same link?  Same link, works vs doesn't work, as it is linked in the sent email.  I link to aspx pages all the time, with tracking, just fine.
