A map of IP addresses of a distributed cloud computing network to one or more groupings is stored. The IP addresses are anycast IP addresses for which compute servers of the distributed cloud computing network share. These IP addresses are to be used as source IP addresses when transmitting traffic to destinations external to the cloud computing network. The map is made available to external destinations. Traffic is received at the distributed cloud computing network that is destined to an external destination. An IP address is selected based on the characteristic(s) applicable for the traffic and the map. The distributed cloud computing network transmits the traffic to the external destination using the selected IP address.

Methods and apparatuses for enabling compatibility between multiple versions of an application programming interface (API) are described. When a first API request is received at a compute server, the compute server determines whether the first API request is of a first version of an API that is different from a second version of the API used in an origin server to which the first API request is destined. In response to determining that the first API request is of the first version of the API that is different from the second version of the API used in the origin server to which the first API request is destined, an API compatibility enabler is executed to convert the first API request into a second API request in the second version of the API. The second API request is fulfilled instead of the first API request.

A method and system for optimization of an advertisement in a network resource in a proxy server of a cloud-based proxy service are described. Responsive to determining that there is an advertisement element in a network resource, the proxy server automatically modifies the advertisement element. The automatic modification of the advertisement element includes: 1) compressing style code into compressed style code; 2) compressing the image; and 3) compressing the style generation code. The proxy server generates a modified version of the network resource including the modified version of the advertisement element, where the modified version of the advertisement element is smaller in size than the advertisement element included in the network resource retrieved from the origin server; and transmits the modified version of the network resource to the client device instead of the network resource.

A method and system for dynamically optimizing a script library are described. A request for a script library is received from a set of client devices. An instrumented version of the script library is transmitted to at least one of the set of client devices. The instrumented version of the script library includes code for tracing execution of the script library. Responsive to execution of the instrumented version of the script library at each one of the at least one of client devices, script library usage feedback indicative of usage of the script library at these client devices is received. An optimized version of the script library, generated based on the script library usage feedback by removing portions of the script library that are unused by the subset of client devices, is transmitted to the client device instead of the script library in response to a second request.
