If you want to use a custom domain name to access the file, bind the custom domain name to the bucket.</p>

<p id="obs_03_0031__p1268192674512">Assume that you have a domain name <strong id="obs_03_0031__b3866548183611">www.example.com</strong> and you upload an image <strong id="obs_03_0031__b1550171510379">image.png</strong> to an OBS bucket. As long as you bind <strong id="obs_03_0031__b19316255153714">www.example.com</strong> to the bucket, you can use <strong id="obs_03_0031__b13967193216388">http://www.example.com/image.png</strong> to access <strong id="obs_03_0031__b6741171917387">image.png</strong>. The steps below describe the configurations:</p>
