Hi where can I find the test-engine ? I would like to copy the code and "play" with it. So I can understand it better . just copying the code is not helpful because I need to understand it. Thanks, Or On Thursday, January 24, 2019 at 11:54:34 PM UTC+2, Matthias Felleisen wrote: > > > Yes

I investigated this (on linux) by killing the process after 1 and after 10 seconds, and both were in the `ssl-connect` function in `openssl/mzssl`. So my guess is it's something there. Sam On Thu, Jan 24, 2019 at 5:07 PM P. Baillet wrote: > > Hello Racketeers, > > With Racket 7.1 on macOS, the

Hello Racketeers, With Racket 7.1 on macOS, the following snippet takes some time to run: ``` #lang racket (require net/url) (require net/url-string) (get-pure-port/headers (string->url "https://video.blender.org;)) ``` ```shell time racket plop.rkt # "Access-Control-Allow-Origin:

Yes there is. Use (require test-engine/racket-tests) at the top and (test) at the bottom. But it sounds like you’re copying and pasting homework solutions. Hmph. > On Jan 24, 2019, at 3:44 PM, orenpa11 wrote: > > Hi Matthias , > Unfortunately I need to write the project in pretty big

An additional reason to do it with Racket's HTTP libraries is so that one bot someday going crazy doesn't make a devops/sysadmin see that it's Racket, and think unhappy thoughts about Racket. :) Agreed. Best regards, Dmitry -- You received this message because you are subscribed to the

Neil, Thank you so much, I did not know that I can play with the header so easily in get-pure-port. It turned out that the server expects "Accept:" field in the request (but does not care much about its value). So the following code works #lang racket (require net/url) (let* ((url
