Hi,

I have a question regarding expire in policy scripts:

If I use:  
&nbsp;&nbsp;global rpc\_calls: table[conn\_id] of table[count] of rpc\_call\_state  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&write\_expire = rpc\_timeout &expire\_func=expire\_rpc\_call;

will the expire timer be linked to the table that's indexed by conn\_id  
or the table that's indexed by count? Can I specify the table that  
should have an expire timer?

I want the timer linked to the table indexed by count.

thanks,  
gregor

Iirc, it applies to the outer one. You can get the inner one by  
assigning the expire to a local and then inserting that into the  
outer table:

&nbsp;&nbsp;&nbsp;&nbsp;local inner: table[count] of rpc\_call\_state &write\_expire=rpc\_timeout;  
&nbsp;&nbsp;&nbsp;&nbsp;rpc\_call[cid] = inner;
