403 errors when referencing theme assets from HTML

Hello,


I have a problem using images and CSS files in master pages. Whenever I link to certain files, eg. a logo using something like:

<img src="/MyProject/App_Data/Sitefinity/WebsiteTemplates/MyTemplate/App_Themes/MyTheme/Images/logo.png" alt="logo"/>

...I get a 403 error for the file. Setting background images from CSS does work. Same goes for <link/> tags in the <head/> element (although auto-include works for Layout.css, so that's what I did for this template).

Is this an effect of a hotlink-protection system in 4.0beta? There's always applying background images through CSS, but IMHO logos and images that are semantically valid should be available to include using master links.

Is there a way around this effect?

Hello Klemen Slavič,

Thank you for using our services.

The App_Data folder is a special folder in ASP.NET with special permissions. Its purpose is to serve as data store (mainly for db files and xml schemas). It is protected from direct linking and probably this is why you are experiencing problems when try references images in App_Data. Can you try copying the images in some other path and linking them?

I see, I've been mislead by the 4.0 beta documentation. Quote:


Example: Including a Reset.css file for a theme as a link.
 
<link href="~/App_Data/Sitefinity/WebsiteTemplates/DefaultTemplate/DefaultTheme/Global/Reset.css" type="text/css" rel="stylesheet" />

Page 7 of Designer's Guide 4.0.

I'll try creating a folder in the root directory and linking from there.

It works now, but the documentation should be updated to reflect this restriction.

Hello Klemen Slavič,

Thank you for getting back to me.

The css files are served because you have registered the theme and Sitefinity is rerouting the paths not to be pointing to App_Data. If you examine the locations of the loaded CSS files on your page they will be something like: /Sitefinity/WebsiteTemplates/University/App_Themes/LightGreen/global/main.css. Also images contained in your theme's css are also rerouted and loaded without the App_Data in the path. So you should be able to link to the image with:

<img src="/MyProject/Sitefinity/WebsiteTemplates/MyTemplate/App_Themes/MyTheme/Images/logo.png" alt="logo"/>

We are going to update our documentation accordingly.

Best wishes,

Yes, that did the trick. Thank you.
