    ImageGen large amount of cached files (NoCache option)

    The <NoCache>True</NoCache> setting causes only that cached files are not used but the files are still generated. I have just more than 100 thousands cached files. When this files aren't distributed thet is is also unefficient.

    For high performance the disc cache is not efficient. Much better is acceleration.

    Please make full sense of NoCache option :)

    I think the manual is clear that 'nocache' doesn't mean that no cache is created... rather, any previously-generated cached image is not used and a new image is generated and cached.

    Disregard any previously-cached image, recreate the image and cache it to disk. Useful for debugging. This setting should not be used in production as it will create new images with every request, slowing performance and using more server resources than necessary.


    If you've got far too many cached images in a folder you may be using an older version of ImageGen that had a bad caching bug? You can check the version in use by using imagegen.ashx?version on the querystring.
