Examples with CacheResult android.webkit.CacheManager.CacheResult used on opensource projects

Example 1 with CacheResult

use of android.webkit.CacheManager.CacheResult in project android_frameworks_base by ParanoidAndroid.

the class HttpHeaderTest method testCacheControlMultipleArguments.

// Test that cache behaves correctly when receiving a compund
// cache-control statement containing no-cache and max-age argument.
//
// If a cache control header contains both a max-age arument and
// a no-cache argument the max-age argument should be ignored.
// The resource can be cached, but a validity check must be done on
// every request. Test case checks that the expiry time is 0 for
// this item, so item will be validated on subsequent requests.
public void testCacheControlMultipleArguments() throws Exception {
    // get private method CacheManager.parseHeaders()
    Method m = CacheManager.class.getDeclaredMethod("parseHeaders", new Class[] { int.class, Headers.class, String.class });

    CacheResult c = (CacheResult) m.invoke(null, 200, h, "text/html");
    // Check that expires is set to 0, to ensure that no-cache has overridden
    // the max-age argument
