[httperf] Size of the request

[Arlitt, Martin]

Hi Rafael

The only way I am aware to do this is to add one or more request headers; for example, in the httperf command line include -add-header="Extra-Header: This is padding\n".

According to Section 7.1 of the HTTP specification (RFC 2616), "unrecognized header fields SHOULD be ignored by the recipient". If the server you are using does not ignore it (resulting in an error rather than a successful transfer of the requested object), then I'm not sure what you can do.

Please keep in mind that HTTP requests are not fixed lengths. Thus if the request URI changes, you may have to revise the added header to keep the overall request size to a desired value (e.g., 150 bytes). If you are using a session-based workload, this approach may not work either.

Also, in case you are not aware, you can use -print-request=header to see the contents of the request being sent to the server, and -print-reply=header to see the response headers that are returned.

Thanks
Martin

No, I'm talking about the request size. As the results shows:

Request size [B]: 62.0

Is it possible change the body of the request to change that 62 bytes to, for example, 150 bytes?

Ok.

I think that Rafael can be confusing request and response.
I imagined that his doubt were about how increase response time of Web Server.

It's just my opinion.

Hi Ricardo

You can add request headers/bodies with httperf. Response headers/bodies are the responsibility of the Web server that httperf contacts.

Thanks
Martin

Hi Rafael

If you are referring to the header sizes, you can add additional headers with -add-header (see the httperf man page about this option). If you are referring to the size of a request body, you can vary the size of the contents that are POSTed to the server (e.g., see the httperf man page on -wsesslog).

Thanks
Martin

Someone knows how could I change the size of the request?
