Vulnerability in EPiServer.Forms
I am developing a site that uses output caching through EPiServer. I need a part of a page (an Extension function) to be excluded from the output cached since it contains a Captcha image. Is there any way to exclude this user control from the output cache?
I have tried the PartialCaching(0) attribute for the Extension function user control, but Extension doesn´t allow this attribute. What to do?
Have look at the asp:Substitution control, it gives you the ability to insert a string into a cached page. I use it on an EPiServer site with caching.
In your case you could insert the url to the Captacha image, or image handler.
Did any of you get the donut caching working successfully? If so, can you provide some additional details on your approach? Thanks!
