<B>DESCRIPTION</B>
|
||
|
|
The Website Configuration feature enables you to configure a Google Cloud
|
||
|
|
Storage bucket to simulate the behavior of a static website. You can define
|
||
|
|
main pages or directory indices (for example, index.html) for buckets and
|
||
|
|
"directories". Also, you can define a custom error page in case a requested
|
||
|
|
resource does not exist.
|
||
|
|
|
||
|
|
The gsutil getwebcfg command gets the web semantics configuration for a
|
||
|
|
bucket, and displays an XML representation of the configuration.
|
||
|
|
|
||
|
|
In Google Cloud Storage, this would look like:
|
||
|
|
|
||
|
|
<?xml version="1.0" ?>
|
||
|
|
<WebsiteConfiguration>
|
||
|
|
<MainPageSuffix>
|
||
|
|
index.html
|
||
|
|
</MainPageSuffix>
|
||
|
|
<NotFoundPage>
|
||
|
|
404.html
|
||
|
|
</NotFoundPage>
|
||
|
|
</WebsiteConfiguration>
