Very little is required to run Rebol CGI scripts under Apache’s HTTP server if you are already running Perl or PHP scripts.

What spooked me was a peculiar echo in my HTML page of

Content-Type: html/text

which I could not shake.

There was an explanation. On my first test I used the singularly unimaginative file name of rebol.r just to be sure that I did not need to use a CGI file extension, e.g., rebol.cgi

Because my initial rebol.r worked fine, I went on to try test_002.r and my problems began …

It turns out that even in a /cgi-bin directory, if Rebol finds a file called Rebol.r then that file is executed before your own file.

Now this could be useful as a default header for all rebol CGI scripts in that directory. But if a script contains its own

prin “Content-Type: text/html”

the ghost will have been inserted into the machine.

Once I had renamed rebol.r to rebol_0001.r all was well. The following test script works fine:

#!I:/rebol/core/rebol.exe -cswq
Rebol [
Title: "CGI test 004"
]
prin "content-type: text/html^/^/"

comment {filename is rebol_004.r
test URl is http://localhost:8080/cgi-bin/Rebol_004.r
}
