Re: [squid-users] Adding Header file

Hi Amos,

With respect to ESI , I am also faced with the following problem. In
the following example the value of "a" that should be printed is 30.
But It prints the value of "a" as 10.
---------------------------------------------------------------------------------
<esi:assign name="a" value="10"/>
<esi:assign name="a" value="20"/>
<esi:assign name="a" value="30"/>

<esi:vars>
name = $(a)
</esi:vars>
----------------------------------------------------------------------------------

It seems that ESI makes use of Trie data structure . Could this be
because the value of the variable doesn't get updated in Trie ? How
can one update a value associated with a variable using Trie ?

Thanks.
