If you need to use 64-bit web 6.1 SP11, you can download it at
https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_SMI-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=SJWS-6.1-SP11-OTH-G-F@CDS-CDS_SMI
This will allow you to use much more in memory address space.
e.g. for a 32-bit process, the theoretical max. memory per process = 4 GB,
a pmap will show,
vm40:/wlee/bits/tmp-web7.0u5> pmap 16908 | more
16908: webservd -d /wlee/7.0u4/run/https-vm40.singapore.sun.com/config -r /wl
00010000 8K r-x-- /wlee/7.0u4/run/lib/webservd
00020000 8K rwx-- /wlee/7.0u4/run/lib/webservd
00022000 56K rwx-- [ heap ]
00030000 3904K rwx-- [ heap ]
00400000 167936K rwx-- [ heap ]
DB87A000 8K rwx-R [ stack tid=285 ]
......(note the above address = 8 * 4-byte each = 32-bit address)
but if we are running 64-bit, then the pmap will show,
vm40:/wlee> pmap 3799 | more
3799: webservd -d /wlee/7.0u5-64/https-vm40.singapore.sun.com/config -r /wle
0000000100000000 8K r-x-- /wlee/7.0u5-64/lib/sparcv9/webservd
0000000100100000 8K rwx-- /wlee/7.0u5-64/lib/sparcv9/webservd
0000000100102000 56K rwx-- [ heap ]
0000000100110000 3008K rwx-- [ heap ]
0000000100400000 217088K rwx-- [ heap ]
FFFFFFFF3FCFA000 8K rw--R [ stack tid=284 ]
......(note the above address = 16 * 4-byte each = 64-bit address), so the theoretical max. memory per process = 16 TB, but of course limited by other factors, e.g. physical RAM and swap space, etc.
If you need more memory for your web server process (assume you do not have any memory leaks in your application, etc), then one option is to run 64-bit process.

If you need to see the incoming request Host header logged in the web server 6.1SPx logs, then you can try below:
add last one below in magnus.conf, i.e. %Req->headers.host%
Init fn="flex-init" access="$accesslog" format.access="%Ses->client.ip% - %Req->vars.auth-user% [%SYSDATE%] \"%Req->reqpb.clf-request%\" %Req->srvhdrs.clf-status% %Req->srvhdrs.content-length% %vsid% %Req->headers.host% "
then it will log the host header of the incoming request, e.g.
apple:/export/home/iws6.1sp10> telnet localhost 60103
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /banner.html HTTP/1.1
Host: dummytest (note this)
HTTP/1.1 200 OK

The log will show,
127.0.0.1 - - [05/Nov/2008:18:45:37 +0800] "GET /banner.html HTTP/1.1" 200 1827 https-sess dummytest
You can see the Host: dummytest in the last column above.

I tried the latest web 6.1 SP9 International Release.
You can download it at
Sun Download link
The installation is the same easy.
It will ask one more question about Default Language.
See ScreenDump118.gif below for the choice of default language.
I tried Traditional Chinese because I am in Hong Kong.
Then, everything works the same well in the installation and later startup.
The good results are now localized default pages and error responses, e.g.
See ScreenDump111.gif below for the default home page after install
See ScreenDump112.gif below for the localized Chinese NOT FOUND error responses after install
I opened the config files and found this below in magnus.conf
DefaultLanguage zh_tw
So, I experimented and tried to change it to
#DefaultLanguage zh_tw
DefaultLanguage ja
then I restarted the web server and hit a page which does not exist.
It will show me Japanese Not Found error responses.
See ScreenDump119.gif below for the JA responses.
Hope this will add more local languages you need in your site.

If you want to block certain file types , e.g. some .ini or .conf files, from outside access in Sun Java System Web Server 6.1 SP9, then you can add <Client> tag into obj.conf, e.g.
.....
NameTrans fn="document-root" root="$docroot"
<Client uri="*.(ini|conf)">
PathCheck fn=deny-existence bong-file="<web install root>/docs/bongfile.html"
</Client>
PathCheck fn="unix-uri-clean"
....
and the bongfile is :
shell> cat bongfile.html
You cannot view this type of files here !!!
If you do not specify the "bong-file=" above, then the users will get the standard "Not Found" error in their browser.
e.g.
<Client uri="*.(ini|conf)">
PathCheck fn=deny-existence
</Client>
then restart the web server and test, e.g.
http://<hostname.domain>/test.conf
or
http://<hostname.domain>/test.ini
will result in the response as set in bongfile.html to prevent users accessing these types of ini/conf files.
Errors logs:
[21/May/2008:14:38:03] security (10791): for host xx.xx.xx.xx trying to GET /test.conf, deny-existence reports: HTTP4129: denying existence of <web root>/docs/test.conf
[21/May/2008:14:41:12] security (10791): for host xx.xx.xx.xx trying to GET /test.ini, deny-existence reports: HTTP4129: denying existence of <web root>/docs/test.ini
This can add security to file types you do not want outside users accidentally access.
