Allow longer query strings than 4096

I stumbled across the request limits for GET http triggered functions and I was wondering whether this limit could be softened.

The use case is, that we want to have a GET function, that accepts a list of IDs to query the database with an "IN" operator. This list of IDs can be of any size.

During development, the local function host did not really bother about the query string length and it worked with a query string larger than 4096 chars. But when deployed to Azure it stopped working with an error message: "The resource has moved". I am using functions v2.

I found the web.config having ``

Now I was wondering, why this small limit and whether it could be raised? The IETF does not specify a limit on query string length, and it feels odd to me to use a POST http trigger for a pure GET operation. :-)

Maybe you have valid reasons for this limitation and can enlighten me :-)
