A WebJames question

Is it possible to access the client’s HTTP header lines from BASIC in the site’s cgi-bin directory? If so, how?

I want to access the user agent string.

I can see how to do it from CGI script files, or SHTML, but I can’t see how to do it from BASIC.

The BASIC runs as a CGI script. So, the same logic should apply. It is too complicated to explain here. But, hhere is an example script in the cgi-lib.

Look in the cgi_lib for CGI_HeaderInMemory%

and then PRINT $CGI_HeaderInMemory%

you will get something like
GET /cgi-bin/error-log?full=FALSE HTTP/1.1 Host: localhost:9000 User-Agent: NetSurf/3.7 (RISC OS) Accept: / Accept-Encoding: gzip Accept-Language: en, *;q=0.1 If-Modified-Since: Mon, 16 Sep 2019 00:02:15 GMT

John, thank you for pointing me in the right direction – I’d never have found it otherwise.

The proper way appears to be to call FNCGI_ReadRequestLine(tag$, next%) with tag$ as the request including the terminating colon (in my case, "User-Agent:") and next% initially 0, until either the function returns a non-empty string (in which case, it’s the value of the header you’ve requested) or next% is -1 (in which case the desired header hasn’t been found).

You’ve helped me; I hope this may help someone else!
