[Feature Request]

[Rtoribiog]

Context / Scenario

That's a feature that already exists in langchain and will be beneficial to save costs. The idea will be to ported from phyton to c#

https://github.com/zilliztech/GPTCache

https://python.langchain.com/docs/integrations/llms/llm_caching/

https://www.mongodb.com/developer/products/atlas/advanced-rag-langchain-mongodb/

The problem

A lot of money and performance is waste answering the same questions again and again

Proposed solution

Be able to save all the queries together with llm responses in some database and try to fetch it first from there, if not then call the LLM, and have some parameters to invalidate or update cache from time to time.

Importance

would be great to have
