## Implemented Interfaces

## Includes

    #include <libsoup/soup.h>

## Description

SoupCache implements a file-based cache for HTTP resources.

## Functions

### soup_cache_new ()

    SoupCache *
    soup_cache_new (const char *cache_dir,
                    SoupCacheType cache_type);

Creates a new SoupCache.

#### Parameters

cache_dir | the directory to store the cached data, or `NULL` to use the default one |
cache_type | the SoupCacheType of the cache |

#### Returns

a new SoupCache

Since 2.34

### soup_cache_flush ()

    void
    soup_cache_flush (SoupCache *cache);

This function will force all pending writes in the `cache` to be committed to disk. For doing so it will iterate the GMainContext associated with `cache` 's session as long as needed.

Contrast with `soup_cache_dump()`, which writes out the cache index file.

#### Parameters

cache | a SoupCache |

Since 2.34

### soup_cache_clear ()

    void
    soup_cache_clear (SoupCache *cache);

Will remove all entries in the `cache` plus all the cache files.

#### Parameters

cache | a SoupCache |

Since 2.34

### soup_cache_dump ()

    void
    soup_cache_dump (SoupCache *cache);

Synchronously writes the cache index out to disk. Contrast with `soup_cache_flush()`, which writes pending cache entries to disk.

You must call this before exiting if you want your cache data to persist between sessions.

#### Parameters

cache | a SoupCache |

Since 2.34.

### soup_cache_load ()

    void
    soup_cache_load (SoupCache *cache);

Loads the contents of `cache` 's index into memory.

#### Parameters

cache | a SoupCache |

Since 2.34

### soup_cache_get_max_size ()

    guint
    soup_cache_get_max_size (SoupCache *cache);

Gets the maximum size of the cache.

#### Parameters

cache | a SoupCache |

#### Returns

the maximum size of the cache, in bytes.

Since 2.34

### soup_cache_set_max_size ()

    void
    soup_cache_set_max_size (SoupCache *cache,
                             guint max_size);

Sets the maximum size of the cache.

#### Parameters

cache | a SoupCache |
max_size | the maximum size of the cache, in bytes |

Since 2.34

## Types and Values

### struct SoupCache

    struct SoupCache;

### enum SoupCacheType

The type of cache; this affects what kinds of responses will be saved.

#### Members

SOUP_CACHE_SINGLE_USER | a single-user cache |
SOUP_CACHE_SHARED | a shared cache |

Since 2.34
