[ic] A different bounce problem.

[Martin Abell]

Christian Gmuender (cg@simultec.ch) recently mentioned a problem with the
bounce tag on a results page:
>> [bounce href="[history-scan exclude=nothing]"]
>> 
>> can lead to a lost of the session_id if the url found in
>> history-scan is not correctly urlencoded (for example
>> contains space characters at product categorys).
>> 
>> This appears only if you do not allow cookies and your
>> server is behind a proxy server.
>> 
>> To prevent this problem write something like:
>> 
>> [seti oldhref][history-scan exclude=nothing][/seti]
>> [calc]
>>           $Scratch->{oldhref} =~ s/ /%20/g; #some
>> encoder         
>>          
>> return;         
>> [/calc]
>> [bounce href="[scratch oldhref]"]
>>

But I had a different problem when I ordered something using IE in Mac OS X:
"the page 'expired' could not be found".  (I anticipate this may be a
problem with other versions of IE.)  I ended up doing something like this
for the bounce in the "set munge_quantity" routine:

    [bounce href="[area href=scan
                        arg=|
                            va=catgy=[value catgy]
                            fi=products
                            st=sql
                            sf=category
                            se=[value catgy]
                            op=em
                            rf=sku
                            tf=sku
                            sp=results
                        |
                        ]"]

If anyone has other thoughts about this, I'd be interested.
