    <p>My application stores images on S3 and then proxies them through Cloudfront. I'm excited to use the new S3 CORS support so that I can use HTML5 canvas methods (which have a cross-origin policy) but can't seem to configure my S3 and Cloudfront correctly. Still running into "Uncaught Error: SECURITY_ERR: DOM Exception 18" when I try to convert an image to a canvas element.</p> <p>Here's what I have so far:</p> <p><strong>S3</strong></p> <pre><code>&lt;CORSConfiguration&gt; &lt;CORSRule&gt; &lt;AllowedOrigin&gt;MY_WEBSITE_URL&lt;/AllowedOrigin&gt; &lt;AllowedMethod&gt;GET&lt;/AllowedMethod&gt; &lt;MaxAgeSeconds&gt;3000&lt;/MaxAgeSeconds&gt; &lt;AllowedHeader&gt;*&lt;/AllowedHeader&gt; &lt;/CORSRule&gt; &lt;CORSRule&gt; &lt;AllowedOrigin&gt;MY_CLOUDFRONT_URL&lt;/AllowedOrigin&gt; &lt;AllowedMethod&gt;GET&lt;/AllowedMethod&gt; &lt;AllowedHeader&gt;*&lt;/AllowedHeader&gt; &lt;/CORSRule&gt; &lt;/CORSConfiguration&gt; </code></pre> <p><strong>Cloudfront</strong></p> <p>Origins</p> <pre><code>Origin Protocol Policy: Match Viewer HTTP Port: 80 HTTPS Port: 443 </code></pre> <p>Behaviors</p> <pre><code>Origin: MY_WEBSITE_URL Object Caching: Use Origin Cache Headers Forward Cookies: None Forward Query Strings: Yes </code></pre> <p><strong>Is there something I'm missing here?</strong></p> <p>UPDATE : Just tried changing the headers to </p> <pre><code>&lt;AllowedHeader&gt;Content-*&lt;/AllowedHeader&gt; &lt;AllowedHeader&gt;Host&lt;/AllowedHeader&gt; </code></pre> <p>based on this question <a href="https://stackoverflow.com/questions/12229844/amazon-s3-cors-cross-origin-resource-sharing-and-firefox-cross-domain-font-loa">Amazon S3 CORS (Cross-Origin Resource Sharing) and Firefox cross-domain font loading</a></p> <p>Still no go.</p> <p>UPDATE: MORE INFO ON REQUEST</p> <pre><code>Request URL:https://d1r5nr1emc2xy5.cloudfront.net/uploaded/BAhbBlsHOgZmSSImMjAxMi8wOS8xMC8xOC81NC80Mi85NC9ncmFzczMuanBnBjoGRVQ/32c0cee8 Request Method:GET Status Code:200 OK (from cache) </code></pre> <p>UPDATE</p> <p>I think maybe my request wasn't correct, so I tried enabling CORS with</p> <pre><code>img.crossOrigin = ''; </code></pre> <p>but then the image doesn't load and I get the error: Cross-origin image load denied by Cross-Origin Resource Sharing policy.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
