I think we need to set the normalized value as we do here

If the method is normalized to _OTHER then should we also include http.request.method_original, that part is not very clear in spec

I think setting "HTTP" like the example you sent is the way to go. Keeping the convention.

@cijothomas @Kielek this would be really useful for us.... can we have it available sooner

@roycald245, one test is failing.

@roycald245, I have made some direct changes to

• handle http method attributes as in RequestDataHelper.SetHttpMethodTag
• fix cashing tags storage
• extend tests

Please double check if you are fine with this solution.

@cijothomas, could you please review?
