True. But it seems relatively trivial to write a filter that would add the originating IP of each request for the base resource, e.g. 'foo.html', to an in-memory list. Then requests for the targeted resource, e.g. 'bar.jpg', can be easily checked against that list and rejected if the request IP isn't present.

Thanks André, urlrewrite seems a suficiant solution for now as I only want to block people if they try and acess the file from outside my domain. If my understanding is correct blocking by IP although harder to fake would prevent them no matter what.

15 second for redeployment is to much
Hello guys. I can't fix my maven2+wicket application to be redeployed less than 15 seconds, but I want it to take 5 seconds at least. Could someone provide the fastest in the world practise of webapp on Tomcat redeployment??? Precondition ( inital deployment): copy war dir with my webapp into tomcat directory. How redeployment time is spent: 1. 5 second (using maven) compile source ( usually it is 1 or 2 files ) 2. 0 second copy *.class file into Tomcat/webapps 3. 5-7 seconds waiting while Tomcat finds that my webapp deployed files are changed 4. 1 seconds takes to undeploy my webapp 5. 3-5 seconds takes to deploy ( really initialize Wicket & Spring Beans frameworks with my data) So it is too much I think.

Re: 15 second for redeployment is to much
Hi. I am far from being the specialist here, but my inner application designer core revolts at the idea of having a thread in Tomcat busy at nothing else but checking 86,400 times a day, just in case you redeploy an application from time to time. There must exist a more efficient mechanism for doing that. One should probably check how the Tomcat Manager deploys an application on-demand, and use the same mechanism e.g. I'm curious to see Chuck's reaction to this thread.

windows 2k3 / Tomcat 6 / IIS configuration - randomly losing sessions
I'll start by giving a brief history: We have multiple sites on our old host that ran under IIS and Resin fine for years, we recently switched to a dedicated server using windows 2k3. Under IIS we installed the isapi connector tool from apache version 1.2.27, and we are currently using tomcat 6 for all our sites. The problem started from day one. each day across all our sites, "some" shoppers will randomly have their carts purged out right in the middle of their checkout process. I have determined this isn't a browser cookie issue, as they had a solid session going otherwise they wouldn't have been able to enter products into their cart and begin the checkout process. I also know customers are within the 30 timeout window as they have emailed us stating not 5 minutes after entering checkout they were sent back to their cart page with an empty cart message. My only conclusion is somehow these customers are losing their sessions and being issued new ones. It seems to do this randomly and I can't seem to replicate the error myself, but I am recording how often it occurs to other people. I'm uncertain who is the culprit here (IIS or Tomcat or TomcatRedirector). I have read other entries with people who have similar problems, but there doesn't seem to be much in the way of solutions. Can anyone please point me in the right direction as to figure out where to go from here? I've reached a dead end, and don't know how to proceed. Thank you for any help or advice anyone can offer me.

Re: 15 second for redeployment is to much
Fix for step 3. Don't wait for Tomcat to detect changes. See http://tomcat.apache.org/tomcat-6.0-doc/manager-howto.html or use org.apache.catalina.ant.ReloadTask (which uses the manager). My compile command automaticly calls this after a succesful compile. Another tip: test business logic (*.java) with junit. Don't start Tomcat for it. And for GUI code you normaly don't need to redeploy your webapp. Tomcat can dynamicly compile jsp and other template engines often can do that too. Ronald.

Iterate LinkedHashMap gives HTTP 500 in a JSP (NPE)
Hi,
I have a problem iterating a LinkedHashMap lhmObject.
The lhmObject.size() gives correct size and lhmObject.keySet().toString gives
the correct values.
However, if I try iterate the object with lhmObject.keySet() with an empty loop:
for (Integer key : lhmObject.keySet() ) { }
or
for (Iterator it = lhmObject.keySet().iterator(); it.hasNext(); ) { }
I get a HTTP 500 - NullPointerException in the JSP page, which has java.util.*
and appropriate for import.
Has anyone seen this before?
