HTTP server functions/web pages
84 FP Web-Server V.2.8
 The functions &Y and &R can be limited with [Add. Range] (see p. 118).
 The name of the CGI function must be in small letters, i.e.
"http://199.199.26.52/PLC?yyy" will not work.
 The PLC address of the &R and &Y commands cannot be replaced by a
variable name, i.e. "http://199.199.26.52/plc?yyyeR'name'=1" will not
work. For further information, refer to Using variable names instead of
absolute PLC addresses (see p. 95).
 If spaces or Japanese characters are used, an error message pops up
before transmission to the FP Web-Server.
 All file names have to correspond to the DOS 8.3 format, i.e. the name
may only have up to 8 characters and the extension (type) only up to 3
characters after the period. (FP-WEB2 (see p. 16): Long file names
without special characters can be used.)
For programming examples in C++ and Java to control PLC flags via the
HTTP function, please refer to the online help under the keyword "Appendix
