adaptive_acceleration

Property Manager name: Adaptive Acceleration
Behavior version: The v2024-01-09 rule format supports the adaptive_acceleration behavior v2.1.
Rule format status: GA, stable
Access: Read/Write
Allowed in includes: No (temporarily)

Adaptive Acceleration uses HTTP/2 server push functionality with Ion properties to pre-position content and improve the performance of HTML page loading based on real user monitoring (RUM) timing data. It also helps browsers to preconnect to content that’s likely needed for upcoming requests. To use this behavior, make sure you enable the http2 behavior. Use the Adaptive Acceleration API to report on the set of assets this feature optimizes.

Option	Type	Description	Requires
`source`	string	The source Adaptive Acceleration uses to gather the real user monitoring timing data, either `mPulse` or `realUserMonitoring`. The recommended `mPulse` option supports all optimizations and requires the `m_pulse` behavior added by default to new Ion properties. The classic `realUserMonitoring` method has been deprecated. If you set it as the data source, make sure you use it with the `real_user_monitoring` behavior.		{"displayType":"string","tag":"input","type":"text"}
`enable_push`	boolean	Recognizes resources like JavaScript, CSS, and images based on gathered timing data and sends these resources to a browser as it's waiting for a response to the initial request for your website or app. See Automatic Server Push for more information.		{"displayType":"boolean","tag":"input","type":"checkbox"}
`enable_preconnect`	boolean	Allows browsers to anticipate what connections your site needs, and establishes those connections ahead of time. See Automatic Preconnect for more information.		{"displayType":"boolean","tag":"input","type":"checkbox"}
`preload_enable`	boolean	Allows browsers to preload necessary fonts before they fetch and process other resources. See Automatic Font Preload for more information.		{"displayType":"boolean","tag":"input","type":"checkbox"}
`ab_logic`	enum	Specifies whether to use Adaptive Acceleration in an A/B testing environment. To include Adaptive Acceleration data in your A/B testing, specify the mode you want to apply. Otherwise, `DISABLED` by default. See Add A/B testing to A2 for details.		{"displayType":"enum","options":["DISABLED","CLOUDLETS","MANUAL"],"tag":"select"}
	`DISABLED`	Disables the use of Adaptive Acceleration in the A/B testing environment. This is the default value.
	`CLOUDLETS`	Applies A/B testing using Cloudlets.
	`MANUAL`	Applies A/B testing by redirecting a request to one of two origin servers, based on the cookie included with the request.
`cookie_name`	string	This specifies the name of the cookie file used for redirecting the requests in the A/B testing environment.	`ab_logic` is `MANUAL`	{"displayType":"string","tag":"input","type":"text"} {"if":{"attribute":"abLogic","op":"eq","value":"MANUAL"}}
`enable_ro`	boolean	Enables the Resource Optimizer, which automates the compression and delivery of your `.css`, `.js`, and `.svg` content using a combination of Brotli and Zopfli compressions. The compression is performed offline, during a time to live that the feature automatically sets. See the `resource_optimizer` and `resource_optimizer_extended_compatibility` behaviors for more details.		{"displayType":"boolean","tag":"input","type":"checkbox"}
`enable_brotli_compression`	boolean	Applies Brotli compression, converting your origin content to cache on edge servers.		{"displayType":"boolean","tag":"input","type":"checkbox"} {"if":{"attribute":"modulesOnContract","op":"contains","scope":"global","value":"Brotli_Compression"}}
`enable_for_noncacheable`	boolean	Applies Brotli compression to non-cacheable content.	`enable_brotli_compression` is `true`	{"displayType":"boolean","tag":"input","type":"checkbox"} {"if":{"op":"and","params":[{"attribute":"enableBrotliCompression","op":"eq","value":true},{"attribute":"modulesOnContract","op":"contains","scope":"global","value":"Brotli_Compression"}]}}
