Because fiber is optimized for high-performance, values returned from fiber.Ctx are not immutable by default and will be re-used across requests. As a rule of thumb, you must only use context values within the handler, and you must not keep any references. As soon as you return from the handler, any values you have obtained from the context will be re-used in future requests and will change below your feet. Here is an example:

Allan, please add details!

Server

Set Data

Just make a POST request to any path:

POST /hi

Hello World!

TTL

By default, the data is kept for 5 minutes. This TTL can be changed via the ttl-parameter.

POST /hi?ttl=1m30s

Hello World!

Encryption

By default, the data is not encrypted. It is not recommended to encrypt the data on server side. The data should always be encrypted on the client side.

However, if this is not possible, the secret-parameter can be used to specify a password with which the data should be encrypted.

POST /hi?secret=s3cr3tp455w0rd

Hello World!

Produces:

gwttKS3Q2l0+YR+jQF/02u3fNVmMIcVOTNSGD5vWfrYTtH8adt8r

Get Data

GET /hi

Hello World!

Encryption

If the data has been encrypted and should be decrypted on the server side (which is not recommended), the "password" can be passed via the secret-parameter. GET /hi

gwttKS3Q2l0+YR+jQF/02u3fNVmMIcVOTNSGD5vWfrYTtH8adt8r

GET /hi?secret=s3cr3tp455w0rd

Hello World!
