rewrites to redirect html and jsps

| hi guys,
Just wondering if you guys can help or have implemented a similar
solution.
Right this is the Scenario, I have IBM IHS server and IBM Websphere V4
running on the same box. An application running say Trade, now I want
to put an outage page up whilst the app is still running in websphere,
so if anyone tries to hit Trade they will be presented with an
outagepage.html for example. I realise you can do this by using these
commands in the httpd.conf file
RewriteEngine on
RewriteCond d:/temp/outagepage.on -f
RewriteRule ^.*/WebSphereSamples/.*$ http://server/outage.html
And this works if some one tries to hit the url
http://server/WebSphereSamples/TradeSample/TradeDocs
But this what DOES NOT work and I have been banging my head against a
wall as to why it doesnt
JSP Request does work when it shouldnt, outage page not shown, jsp is
still delivered!!!
http://server/WebSphereSamples/TradeSample/welcome.jsp
So why is the rewrite rule working for html requests and not JSPs?
cheers in advance
Mark

| Is the static html being served via the webserver and the dynamic
content being served via websphere? It appears that the loadModule for
websphere is handling the request prior to this rewrite condition for
the dynamic content.

| Hiya Todd
yes you are right static html served by the webserver and the dynamic
content by websphere.
Yes it seems the loadmodule is handling the request first, I thought
to get over this particular problem the 'rewrite' has to appear after
the loadModule in the HTTPD.conf file, excerpt below, but this still
doesnt work  , any ideas
how to get around this
</files>
LoadModule ibm_app_server_http_module
d:/WebSphere/AppServer/bin/mod_ibm_app_server_http.dll
WebSpherePluginConfig d:\WebSphere\AppServer\config\plugin-cfg.xml
Alias /WebSphereSamples/TradeSample/
"d:/http_docs/TradeApp/WebsphereSamples/TradeSample/"
<Directory />
Options -Indexes
</Directory>
AddModule mod_rewrite.c
AddModule mod_alias.c
Alias /icons/ "d:/IBM HTTP Server/icons/"
Alias /IBMWebAS/ "d:/WebSphere/AppServer/web/"
Alias /WSsamples "d:/WebSphere/AppServer/WSsamples/"
ScriptAlias /cgi-bin/ "d:/IBM HTTP Server/cgi-bin/"
RewriteEngine on
#RewriteCond d:/temp/outagepage.on -f - needs to be paired with a
RewriteRule
RewriteCond d:/temp/outagepage.on -f
RewriteRule ^.*/WebSphereSamples/.*$ http://server/outage.html

You could use mod_proxy instead of the WAS plugin. All content would be
served by WebSphere, but you wouldn't have the plugin interferring.

| This would have been an option Aaron , but this is a test box, we are
hoping to progress this outage page mechanism to a production strength
environment where we have a seperate webserver in a DMZ and the
Websphere box on an internal box,
do you think there is a problem with the Rewrite module itself?
cheers

No. I've had the same problem in the past. The WAS plugin just
intercepts the message before most other modules can get to it.
My experience has been with IHS, IHS 2 may have a different behavior.

| May not be the case here, but I'll mention that mod_rewrite only appears
to work for/on/with static resources.
Fought with something similar to your problem on the 400.
