Hi,
I am new to Openwrt platform and face issues with working with uhttpd server for running REST based cgi get/post calls ported from tinyhttp server.
My problem is cgi-get call query delimiter ? is not working in openwrt uhttpd server.
http://<192.168.1.1>/cgi-bin/pre_login_status_app.cgi?sts
returns as
{"result":1,"reason":5,"errorstr":"pre_login_status_app.cgi:argc:1 argv[0]:/www/cgi-bin/pre_login_status_app.cgi argv[1]:(null)"}
=> ?sts is not being detected as separate string and only obtained as null
Other different combintions return error by http server itself

<>Not Found<>The requested URL /cgi-bin/pre_login_status_app.cgi;sts was not found on this server.
