Add Cache-Control and Expires headers to Azure Storage Blobs

Question

I\'m using Azure Storage to serve up static file blobs but I\'d like to add a Cache-Control and Expires header to the files/blobs when served up to reduce bandwidth costs.

Answer 1

This might be too late to answer, but recently I wanted to do the same in different manner, where I have list of images and needed to apply using powershell script (of course with the help of Azure storage assembly) Hope someone will find this useful in future.

Complete explanation given in Set Azure blob cache-control using powershell script

Add-Type -Path "C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.3\ref\Microsoft.WindowsAzure.StorageClient.dll"

$accountName = "[azureaccountname]"
$accountKey = "[azureaccountkey]"
$blobContainerName = "images"

$storageCredentials = New-Object Microsoft.WindowsAzure.StorageCredentialsAccountAndKey -ArgumentList $accountName,$accountKey
$storageAccount = New-Object Microsoft.WindowsAzure.CloudStorageAccount -ArgumentList $storageCredentials,$true
#$blobClient = $storageAccount.CreateCloudBlobClient()
$blobClient =  [Microsoft.WindowsAzure.StorageClient.CloudStorageAccountStorageClientExtensions]::CreateCloudBlobClient($storageAccount)

$cacheControlValue = "public, max-age=604800"

echo "Setting cache control: $cacheControlValue"

Get-Content "imagelist.txt" | foreach {     
    $blobName = "$blobContainerName/$_".Trim()
    echo $blobName
    $blob = $blobClient.GetBlobReference($blobName)
    $blob.Properties.CacheControl = $cacheControlValue
    $blob.SetProperties()
}
