Invalidate Instant Campaign Content in DXA 2.2 . Sites 9.1

Question

I am using Instant Campaign module for managing the landing pages comes as zip package. I am facing one issue while updating the content of the page.

Once I publish the page and request the page I see there is a folder created automatically which contains zip content.

Path of the directory : \<ApplicationFolder>\BinaryData\<folder with Publication Tcm ID as folder name>\campaign-content\<folder with Component TCMID as folder name>

In order to have the updated content I have to follow the below steps:

1. Delete the folder which contains the actual content
2. Recycle the app pool
3. Request the page

After executing the above steps I see the folder is again created with updated content.

Is there any other way to invalidate the cache. As for other normal DXA pages I don't see any issue with content updation. These contents are automatically updated after publishing. (Using AMQ service).

What I observed the page is being cached at IIS level. Even if I delete the folder the page works fine as it is being cached at IIS.

Can any one suggest how to handle this. As recycling the app pool is not a good practice after each content Publish.

Answer 1

What content are you changing? The uploaded campaign ZIP or the textual content stored in Tridion? Instant Campaign is checking the timestamp on the ZIP file (which handled as any other media asset in DXA). If that has changed, the ZIP file will be re-extracted again. Can you verify that the timestamp of the ZIP has changed or not under BinaryData/[publication]/media?

The textual content is handled as ordinary DXA entity, which means it should be available in the same pace as other content (depending on your view model caching etc).
