How to Generate URL for Amazon S3 file?

1 ˆ . Http URL : It is most common and popular format of URL. If you attempt to access the URL that is expired, you will only find some error message. You still keep the file in your S3 account and don't have to remove it in order to remove access for others. click on ‘HTTP URL' radio button to get the http:// format.

2 ˆ . Https URL : It is also http url but works over secure socket layer. In other words, https works over secure mechanism. It is useful where user want secure communication of response/request between client servers. Generally it is used with commercial exchange of data. To generate https URL, you need to click on ‘HTTPS URL' radio button to get the https:// format.

3 ˆ . Default URL : This type of url is used to generate simple url of the selected domain name with http/https protocols.

Url Format : http://<domainname>/objectname
i.e. if you select cloudfront domain then your url will be http(s)://sdk3sf3sdfk3dsf.cloudfront.net/index.html.

4 ˆ . Use Bucket Name as Virtual Host : By this option, Bucket Explorer replaces s3.amazonaws.com with bucket name and construct the URL like your host (website name) URL. But make sure the bucket name should be same as host name ( e.g images.bucketexplorer.com). After generating Virtual Host url you should use CNAME entry otherwise url will not work.

Url Format : http://<domainname>/objectname ( excluded ".s3.amazonaws.com" from Bucket Name )
i.e.   http:// mybucket / myobject.ext , here mybucket and myobject.ext are represented viz; bucket name and file name with extension.

5 ˆ . Torrent URL : ‘Torrent URL' generates a URL that is in the form of Bit Torrent file. Using this URL, object can be downloaded with a Bit Torrent client application. Since this application fetches data from various sources, it saves both time and bandwidth usage. It also eliminates the dependency from the particular host. To generate the torrent URL you need to click on “Torrent Url” button and you will get the url(s) with " ?torrent " suffix.

Url Format : http://<domainname>/objectname?torrent
i.e.  https://mybucket.s3.amazonaws.com/myobject.ext ?torrent

6 ˆ . Signed URL :‘Signed URL' is the url which is valid for specific time period that's why its also know as " Time Limited Signed URL ". Using Bucket Explorer you can set a fixed expiration time for a URL. Upon expiry, the URL will no longer remain active and if you attempt to access the URL once it has been expired, you will only find some error message. You still keep the file in your S3 account and you don't have to remove it from S3 account in order to remove access for others.
The very purpose of signed URL is to share the pages that have time sensitive information, or when you want to share a file with someone without making it available to everyone on the net. Such information becomes stale once a definite time passes out.

Url Format : http://<domainname>/objectname ?AWSAccessKeyId =<accesskey>& Expires =<expire time>& Signature =<signature string>
i.e.  https://mybucket.s3.amazonaws.com/myobject.ext? AWSAccessKeyId =ALSECKCKDKMKC5GUSNFA& Expires =1301234062& Signature =ssmu34aCsECO8%2F6vHDdf9u0TCcU%3D
