Re: [Pharo-users] ZnClient 403 but 200 in Firefox
Hi Hernan, quite interesting. I have tried with curl and it works, but with wget it doesn't work. Both using the brew versions in my OSX machine. To me, it is a problem of the headers. Cheers.

Re: [Pharo-users] ZnClient 403 but 200 in Firefox
It is done very often. In the past you could solve glitches between browser engines. Nowadays it is done e.g. to discover mobile clients. In one of my services the easiest to keep foreigners out was rejecting all requests which are not zinc 😉 Norbert > Am 11.10.2018 um 00:32 schrieb Hernán Morales Durand > : > > Wow, didn't knew that someone actually could reject/allow specific UAs. > > Thank you Sven, > > Cheers, > > Hernán > El mié., 10 oct. 2018 a las 17:33, Sven Van Caekenberghe > () escribió: >> >> Because they don't like Pharo or Zinc ;-) >> >> ZnClient new >> systemPolicy; >> beOneShot; >> url: 'http://ifconfig.me/ip'; >> accept: ZnMimeType textPlain; >> headerAt: 'User-Agent' put: 'curl/7.54.0'; >> get. >> >> Changing the User-Agent (effectively lying) works. >> >>> On 10 Oct 2018, at 22:02, Hernán Morales Durand >>> wrote: >>> >>> When I visit this site http://ifconfig.me/ip using the web browser I >>> get the expected text output.

Because they don't like Pharo or Zinc ;-) ZnClient new systemPolicy; beOneShot; url: 'http://ifconfig.me/ip'; accept: ZnMimeType textPlain; headerAt: 'User-Agent' put: 'curl/7.54.0'; get.
