When this variable is set to "1" (on, true, yes), the runtime automatically
removes carriage return characters from data entered in HTML TEXTAREAS (multiple
line entry-fields). Stripping the carriage returns from this kind of input
prevents double-spacing problems, as well as conflicts that may arise if the data
is used in a context that does not expect a carriage return character to
precede each line feed character. Some browsers send a carriage return line feed
sequence to the CGI program, and when this sequence is written to a file on
operating systems that terminate text lines with line feed characters only, the file
may appear to be double spaced. The default value is "0" (off, false, no).
For example, if you enter the following three lines in a TEXTAREA for a field
called "thetext":
Sometext line 1 Sometext line 2 Sometext line 3
The browser sends the following to the CGI program:
thetext=Sometext+line+1%0D%0ASometext+line+2%0D%0ASometext+line+3%0D%0A
If the CGI_STRIP_CR is set to "1" (on, true, yes), the runtime strips the carriage return characters so that the input line is the following:
thetext=Sometext+line+1%0ASometext+line+2%0ASometext+line+3%0A
