Campaign Caching for Solution Sites

  • Article

The Solution Sites provide two caches for advertisements and discounts that are used by the Content Selection Framework (CSF). Site developers do not need to reference these caches. Unlike the catalog caches, these caches use Dictionary objects, so they are initialized in a slightly different way.

Advertisement Cache

Discounts Cache

Initialization

The following code, from the InitCacheManager function, shows the creation of the advertising cache:

'Create the configuration dictionary.
    Set dictCampaignConfig = GetDictionary()
    dictCampaignConfig("ConnectionString") = _
        dictConfig.s_CampaignsConnectionString
    Set dictCampaignConfig("Evaluator") = oEvaluator
        ' oEvaluator is the Commerce Server ExpressionEvaluator.

    ' Configure CacheManager for ads.
    oCacheManager.RefreshInterval("advertising") = 5*60
    oCacheManager.RetryInterval("advertising") = 60
    oCacheManager.LoaderProgId("advertising") = _
        "Commerce.CSFLoadAdvertisements"
    oCacheManager.WriterProgId("advertising") = "Commerce.CSFWriteEvents"
    Set oCacheManager.LoaderConfig("advertising") = dictCampaignConfig
    Set oCacheManager.WriterConfig("advertising") = dictCampaignConfig

Discounts Cache

Initialization

The following code, from the InitCacheManager function, shows the creation of the discounts cache:

'Create the configuration dictionary.
    Set dictCampaignConfig = GetDictionary()
    dictCampaignConfig("ConnectionString") = _
        dictConfig.s_CampaignsConnectionString
    Set dictCampaignConfig("Evaluator") = oEvaluator
        ' oEvaluator is the Commerce Server ExpressionEvaluator.

'Configure CacheManager for discounts.
    'Setting RefreshInterval to 0 disables automatic refreshing.
    oCacheManager.RefreshInterval("discounts") = 0
    oCacheManager.RetryInterval("discounts") = 60    'seconds
    oCacheManager.LoaderProgId("discounts") = "Commerce.CSFLoadDiscounts"
    oCacheManager.WriterProgId("discounts") = "Commerce.CSFWriteEvents"
    Set oCacheManager.LoaderConfig("discounts") = dictCampaignConfig
    Set oCacheManager.WriterConfig("discounts") = dictCampaignConfig
