Please describe.**\r\nWhen the content request comes in and the processing will be delayed, duplicating the memory creates memory pressure.  I would like to be able to swap the content string into my own string so I don't have to make a copy, but I plan to return the response to the sender before completion (which in my case is a re-direct)\r\n\r\n**Describe why the feature or enhancement you are proposing fits the library.**\r\nThe content is not necessary to be used by the library once I have received it\r\n\r\n**Describe the solution you'd like**\r\nEither I'd like to be able to get a non-constant pointer to the content, or a way to pass my std::string for the swap within the lirbary\r\n\r\n**Describe alternatives you've considered**\r\nI make a copy now.  I've considered just modifying the code I have myself and still might.  I could easily submit a PR for this but have not contributed to this project before\r\n\r\n**Additional context**\r\nAdd any other context or screenshots about the feature request here.\r\n","author":{"url":"https://github.com/btiplitz","@type":"Person","name":"btiplitz"},"datePublished":"2022-06-03T18:11:17.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/272/libhttpserver/issues/272"}
