Problem putting large files

I tried to upload a large file (2k) using a PUT-Request.

The server respond with '400 BadRequest: Too large request line'.

I found out that HttpParsers request limit is set to 4196.

My questions are:

- Why is the limit set to 4196 ?

- Did you see a possibility to upload large files via PUT ?


thanks in advance.

Send the contents in the body if possible.


Don't remember why I set that limit. But the request line shouldn't be used to put large information. The parser isn't built for that.

thank you for your answer.

For me it is very important to know wether i could upload gifs via PUT-Request or not.

You wrote: 'Send the contents in the body if possible.'

An example of an PUT-Request i sent is:


PUT /img/test.gif HTTP/1.1
Connection: Keep-Alive
Content-Type: image/gif
Content-Length: 2048


For my understanding the gif is in the body.

I want understand you right, could you please give me an answer to clarify this ?

Thank you in advance.

Yes. You are sending it as a body. Then it's a bug in the parser.

"Too large request line" should only be sent if "PUT /img/test.gif HTTP/1.1" are larger than 4196 bytes.
