New Post: Custom 404 is set and handles also httphandlers

Hello,

I have a composite C1 website where the 'custom 404 page' is set.

Then in the web.config I have a httphandler for a specific file (export.csv). When a request is coming for export.csv, the httphandler doesn't take the request but Composite. And Composite cannot find the page and the custom 404 page will be happening.

When I remove the custom 404 page, the export.csv httphandler will handeling the request.

How can I configure Composite that Composite not handle some file-(extensions)?
