Cristina> Hello!!
Cristina> I'm doing an application (Criminal law Course) in CL-HTTP
under
Cristina> LispWork of Harlequin, but i've a problem. I'm going to show you
part of the
Cristina> code. I 've a html page, siidepe.html
Cristina> ...........
Cristina> <FORM ACTION="curso.html" METHOD="POST">
Cristina> user<INPUT TYPE="text" NAME="NOMBRE" SIZE="10" VALUE="">
Cristina> password<INPUT TYPE="passwd" NAME="NOMBRE" SIZE="10" VALUE="">
Cristina> ......
Cristina> And when i submitted this form, the response function read
from a
Cristina> file which contain information of the user that do the course (the
last page
Cristina> visited, what they know about each topic,the pages that are known
for them),
Cristina> and this information is saved in global variables
Cristina> (usuario,clave,pagnum,pagin,tema1,..).And i think this don't work
when there
Cristina> are 2 o more users using the course. So, can you advice me how can
i do what
Cristina> i want?.
Cristina> Note: I 've to use the file, to save the information of the users.
CL-HTTP is multithreaded, so different threads might update the file
simultaneously. Perhaps you need to use a lock to control access to the file?
See the macros MP:WITH-LOCK or CLIM-SYS:WITH-LOCK-HELD.
