Yes, I can explain it more clearly
PC(s) --------(LAN/WAN)-------XAMPP web server( 10.1.1.1)
There is some sort of old stupid software that installed on several PCs at my office branches, it need to download a data file from our web server to process. But when using its web interface to get data, it will request something like : http://10.1.1.1/pcid=xxxxx(
for example : PC A will request : http://10.1.1.1/pcid=11112
, PC A will request : http://10.1.1.1/pcid=12222..
.) while in true, all it need is request : http://10.1.1.1/data.xls
to get the data file.
Because the software is hardcode, so I can't change it, so I need to find a way to change its request when it get to web server, I want on web server, when it receive a request like : http://10.1.1.1/pcid=xxxxx(
xxxxx maybe abcds, 12223,22333...) it will always return a file name data.xls.
I hope now I make it clear enough
