CF8 - cfimage captcha suddenly stopped displaying

[Kristin Gitler]

Hi All,

 

I have 2 sites on the same CF8 (Windows/ IIS) server that I have been using the cfimage tag to create a captcha image.  It has been working fine, and suddenly, at some point in the last 2 weeks, the image stopped displaying.  I have made no changes in the code or settings, and the host tells me that they have not done any updates (either CF or Windows).

 

What you see in the browser is a broken image.  When you view the source, the image is referenced like this:   img src="/CFFileServlet/_cf_captcha/_captcha_img7929489215261314835.png"

 

If I try to view the image at that url (with the web root), I get a “not found”.

 

When I look on the server, I find the image here: ColdFusion8/tmpCache/CFFileServlet/_cf_captcha

 

I don’t have ISAPI Rewrite or IISRewrite or anything like that running on the server.

 

Why, if there have been no updates, would it suddenly stop working?   Do I need to create a mapping for the folder? (and why now?).

 

Thanks for any help you can provide.
