Interface ICacheSpecs

Namespace

ToSic.Sxc.Services.Cache

Assembly

ToSic.Sxc.dll

Cache Specs contain the definition of what the cached data should depend on, how long it should be cached and how the cache key should be generated. It uses a fluent API to continue adding rules / expirations / dependencies. Internally this is then used to create a cache policy.

[PublicApi]
public interface ICacheSpecs

Remarks

• Introduced as experimental in v17.09
• Released in 19.01

Methods

SetAbsoluteExpiration(DateTimeOffset)

Set absolute expiration, alternative is sliding expiration. If neither are set, a sliding expiration of 1 hour will be used.

ICacheSpecs SetAbsoluteExpiration(DateTimeOffset absoluteExpiration)

Parameters

absoluteExpiration DateTimeOffset

Returns

ICacheSpecs

Remarks

If neither absolute nor sliding are set, a sliding expiration of 1 hour will be used. Setting both is invalid and will throw an exception.

SetSlidingExpiration(TimeSpan)

Set sliding expiration, alternative is absolute expiration.

ICacheSpecs SetSlidingExpiration(TimeSpan slidingExpiration)

Parameters

slidingExpiration TimeSpan

Returns

ICacheSpecs

Remarks

If neither absolute nor sliding are set, a sliding expiration of 1 hour will be used. Setting both is invalid and will throw an exception.

VaryBy(string, int)

Vary the cache by a specific name and value. All cache items where this value is the same, will be considered the same. For example, this could be a category name or something where the data for this category is always the same.

ICacheSpecs VaryBy(string name, int value)

Parameters

name string

value int

Returns

ICacheSpecs

VaryBy(string, string, NoParamOrder, bool)

Vary the cache by a specific name and value. All cache items where this value is the same, will be considered the same. For example, this could be a category name or something where the data for this category is always the same.

ICacheSpecs VaryBy(string name, string value, NoParamOrder protector = default, bool caseSensitive = false)

Parameters

name string

value string

protector NoParamOrder

see Convention: Named Parameters

caseSensitive bool

Returns

ICacheSpecs

VaryByModule()

Vary the cache by the current module, so that each module has its own cache.

ICacheSpecs VaryByModule()

Returns

ICacheSpecs

VaryByModule(int)

Vary the cache by module, so that each module has its own cache.

ICacheSpecs VaryByModule(int id)

Parameters

id int

Module id to use

Returns

ICacheSpecs

VaryByPage()

Vary the cache by the current page, so that each page has its own cache.

ICacheSpecs VaryByPage()

Returns

ICacheSpecs

VaryByPage(int)

Vary the cache by page, so that each page has its own cache. By default, it will take the current page, but you can optionally specify a custom page or ID.

ICacheSpecs VaryByPage(int id)

Parameters

id int

page id to use

Returns

ICacheSpecs

VaryByPageParameters(string, NoParamOrder, bool)

Vary the cache by one or more specific page parameter, like ?category=1 or ?category=1&sort=asc. Using this method will only vary the cache by the mentioned parameters and ignore the rest.

ICacheSpecs VaryByPageParameters(string names = null, NoParamOrder protector = default, bool caseSensitive = false)

Parameters

names string

Names of one or more parameters, comma-separated. If null, all parameters are used, if "", no parameters are used.

protector NoParamOrder

see Convention: Named Parameters

caseSensitive bool

Determines if the value should be treated case-sensitive, default is false

Returns

ICacheSpecs

VaryByParameters(IParameters, NoParamOrder, string, bool)

Vary the cache by a custom parameters list.

ICacheSpecs VaryByParameters(IParameters parameters, NoParamOrder protector = default, string names = null, bool caseSensitive = false)

Parameters

parameters IParameters

parameters object

protector NoParamOrder

see Convention: Named Parameters

names string

Names of one or more parameters, comma-separated

caseSensitive bool

Determines if the value should be treated case-sensitive, default is false

Returns

ICacheSpecs

VaryByUser()

Vary the cache by current user, so that each user has its own cache.

ICacheSpecs VaryByUser()

Returns

ICacheSpecs

VaryByUser(int)

Vary the cache by user, so that each user has its own cache.

ICacheSpecs VaryByUser(int id)

Parameters

id int

User id to use

Returns

ICacheSpecs

WatchAppData(NoParamOrder)

Depend on the app data, so if any data changes, the cache will be invalidated.

ICacheSpecs WatchAppData(NoParamOrder protector = default)

Parameters

protector NoParamOrder

Returns

ICacheSpecs

WatchAppFolder(NoParamOrder, bool?)

Depend on the app folder, so if any file in the app folder changes, the cache will be invalidated. WIP!

ICacheSpecs WatchAppFolder(NoParamOrder protector = default, bool? withSubfolders = null)

Parameters

protector NoParamOrder

see Convention: Named Parameters

withSubfolders bool?

should it also watch subfolders? default is true

Returns

ICacheSpecs
