1. Overload¶

public static IObservable<byte[]> DownloadUrl(this IBlobCache blobCache, string url, HttpMethod? method = null, IEnumerable<KeyValuePair<string, string>>? headers = null, bool fetchAlways = false, DateTimeOffset? absoluteExpiration = null)

View source

Summary: Downloads data from an HTTP URL and inserts the result into the cache. If the data is already in the cache, this returns a cached value. The URL itself is used as the cache key.

Parameters

Name	Type	Description
`blobCache`	[IBlobCache](#	The blob cache to perform the operation on.
`url`	string	The URL to download.
`method = null`	HttpMethod?	The HTTP method to use for the request.
`headers = null`	IEnumerable>?	An optional collection containing HTTP request headers.
`fetchAlways = false`	bool	A value indicating whether to force a web request to always be issued, skipping the cache.
`absoluteExpiration = null`	DateTimeOffset?	An optional expiration date for the cached data.

Returns: IObservable -- An observable that emits the data downloaded from the URL.

2. Overload¶

public static IObservable<byte[]> DownloadUrl(this IBlobCache blobCache, Uri url, HttpMethod? method = null, IEnumerable<KeyValuePair<string, string>>? headers = null, bool fetchAlways = false, DateTimeOffset? absoluteExpiration = null)

`fetchAlways = false`	bool	Force a web request to always be issued, skipping the cache.
`absoluteExpiration = null`	DateTimeOffset?	An optional expiration date.

Returns: IObservable -- The data downloaded from the URL.

3. Overload¶

public static IObservable<byte[]> DownloadUrl(this IBlobCache blobCache, string key, string url, HttpMethod? method = null, IEnumerable<KeyValuePair<string, string>>? headers = null, bool fetchAlways = false, DateTimeOffset? absoluteExpiration = null)

View source

Summary: Download data from an HTTP URL and insert the result into the cache. If the data is already in the cache, this returns a cached value. An explicit key is provided rather than the URL itself.

Parameters
