    ImageGen and robots.txt


    I have setup my robots.txt like this :

    User-agent: *
    Disallow: /umbraco/

    However, the pictures are not parsed by google bot. I guess it's because Imagegen is in the /umbraco folder which is deny.

    So i added at the end

    Allow: /umbraco/ImageGen.ashx*

    but it still doesn't work.

    Any ideas ?

    Thank you very much

    If you use a newer version of ImageGen you'll find it installs into the root of your site at /imagegen.ashx so you won't have to worry about disallowing /umbraco/ folder.

    I'm no expert on what google does and doesn't parse but it might be that Google just doesn't parse ashx files with querystring params. Or maybe they do. I don't know. Maybe someone else does. Or a search online to find the answer to what Google does and doesn't do. Do let us know what you find out.

    I have put an HttpModule to load ImageGen so google does not see /ImageGen.ashx?... but it sees /images/myimage?width=xxx

    You can find an example of it in uBootstrap source code.

    I have modified the version of uBootstrap to not check the physical existence of the file in the module for performance reason.
