Abstract

A first server may receive, from a client device, an indication of a request for a content file via a network address; identify that the network address is a dynamic network address; establish a communication session with a second; receive a portion of the content file from the second server; determine an index parameter based on receiving the portion of the content file; determine whether the content file is being stored by the first server based on a cache index and based on the index parameter or based on information associated with the request for the content file; receive a remaining portion of the content file based on determining that the content file is not being stored by the first server; and provide the content file to the client device.

Claims

1. A method comprising:

receiving, by a server and from an origin device that provides a content file to the server, information that identifies a format of a dynamic address,

the dynamic address being separate from the information that identifies the format of the dynamic address;

determining, by the server and based on the information that identifies the format of the dynamic address, the format of the dynamic address;

receiving, by the server, an indication of a request for a content file when a client device requests the content file using a network address;

determining, by the server and after receiving the indication, that the network address is the dynamic address based on the format of the dynamic address;

determining, by the server, a static portion of the network address based on determining that the network address is the dynamic address; and

providing, by the server, the content file to the client device based on the static portion of the network address.

2. The method of claim 1, further comprising:

determining a session identifier included in the network address,

where determining that the network address is the dynamic address comprises;

determining that the network address is the dynamic address based on the format of the dynamic address and the session identifier.

3. The method of claim 1, further comprising:

determining a hash code included in the network address,

where determining that the network address is the dynamic address comprises;

determining that the network address is the dynamic address based on the format of the dynamic address and the hash code.

4. The method of claim 1, further comprising:

removing a dynamic portion of the network address based on determining that the network address is the dynamic address.

5. The method of claim 1, where the static portion of the network address corresponds to a domain of the origin device associated with the content file.

6. The method of claim 1, further comprising:

identifying a cache hit based on the static portion of the network address,

where providing the content file to the client device comprises;

providing the content file to the client device based on identifying the cache hit.

7. The method of claim 1, further comprising:

receiving, from the origin device, a portion of the content file when the client device requests the content file;

identifying a response value based on the portion of the content file; and

determining that the content file is stored by the server based on the response value and the static portion of the network address.

8. The method of claim 1, where the dynamic address includes at least one of:

a universal resource identifier (URI), or

an Internet Protocol (IP) address.

9. A system comprising:

one or more processors, implemented at least partially in hardware, to;

receive, from an origin device that provides a content file to a server, information that identifies a format of a dynamic address,

the dynamic address being separate from the information that identifies the format of the dynamic address;

determine, based on the information that identifies the format of the dynamic address, the format of the dynamic address;

receive an indication of a request for a content file when a client device requests the content file using a network address;

determine, after receiving the indication, that the network address is the dynamic address based on the format of the dynamic address; and

provide the content file to the client device based on determining that the network address is the dynamic address.

10. The system of claim 9,

where the one or more processors are further to:

determine a static portion of the network address based on determining that the network address is the dynamic address, and

where, when providing the content file, the one or more processors are to;

provide the content file to the client device based on the static portion of the network address.

11. The system of claim 9,

where the one or more processors are further to:

determine a response value based on a portion of the content file;

determine a request value based on determining that the network address is the dynamic address; and

determine that the content file is stored in a cache of the system based on the response value and based on the request value, and

where, when providing the content file, the one or more processors are to;

provide the content file to the client device based on determining that the content file is stored in the cache of the system.

12. The system of claim 9, where the one or more processors are further to:

terminate, based on determining that the network address is the dynamic address, a communication session with the origin device associated with the content file in a manner that prevents additional data being received from the origin device.

13. The system of claim 9,

where the one or more processors are further to:

determine that the content file is not stored in a cache of the system based on determining that the network address is the dynamic address, and

where, when providing the content file, the one or more processors are to;

provide the content file to the client device based on determining that the content file is not stored in the cache of the system.

14. The system of claim 13, where the one or more processors are further to:

receive a portion of the content file based on determining that the content file is not stored in the cache of the system; and

store the content file in the cache of the system after receiving the portion of the content file.

15. The system of claim 9, where the dynamic address includes at least one of:

a universal resource identifier (URI), or

an Internet Protocol (IP) address.

16. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by at least one processor, cause the at least one processor to;

receive, from an origin device that provides a content file to a server, information that identifies a format of a dynamic address,

the dynamic address being separate from the information that identifies the format of the dynamic address;

determine, based on the information that identifies the format of the dynamic address, the format of the dynamic address;

determine that a network address, associated with a request for a content file, is the dynamic address based on the format of the dynamic address;

determine a static portion of the network address based on determining that the network address is the dynamic address; and

provide the content file to a client device based on the static portion of the network address.

17. The non-transitory computer-readable medium of claim 16, where the one or more instructions to determine that the network address is the dynamic address comprises:

one or more instructions that, when executed by the at least one processor, cause the at least one processor to;

receive an indication of the request for the content file when the client device requests the content file using the network address; and

determine, after receiving the indication, that the network address is the dynamic address based on the format of the dynamic address.

18. The non-transitory computer-readable medium of claim 16,

where the instructions further comprise:

one or more instructions that, when executed by the at least one processor, cause the at least one processor to;

identify a format of a session identifier based on the information that identifies the format of the dynamic address; and

determine the session identifier in the network address based on identifying the format of the session identifier, and

where the one or more instructions to determine that the network address is the dynamic address comprise;

one or more instructions that, when executed by the at least one processor, cause the at least one processor to;

determine that the network address is the dynamic address based on the session identifier.

19. The non-transitory computer-readable medium of claim 16,

where the instructions further comprise:

one or more instructions that, when executed by the at least one processor, cause the at least one processor to;

identify a cache miss based on the static portion of the network address, and
