Securing JSESSIONID cookie if tomcat is fronted by apache

In my previous post Creating a custom Valve in tomcat I descibed the valve solution I tried to secure the JSESSIONID cookie but it didnt worked so finally I had to patch the tomcat class to get it working. We are using tomcat 5.5.28 so I downloaded the source and modify the class apache-tomcat-5.5.24-src/container/catalina/src/share/org/apache/catalina/connector/Response.java. In addCookie method I had to add this code


 String cookieName = cookie.getName();
 if (request != null && "JSESSIONID".equals(cookieName)) {
    String clientId = request.getHeader("X-Forwarded-For");
    if (clientId != null) {
  cookie.setSecure(true);
    }
 } 


Then compile the code and replace the catalina.jar in tomcathome/server/lib

  2. no no its not a tomcat bug, but its the way we put apache/nginx in front of tomcat so that we don't want tomcat to handle SSL traffic. Apache handles SSL and by the time it reaches tomcat the request is no longer secure and thats why tomcat was not creating secure cookie. So it was a workaround to do it. This can also be used to set JSESSIONID a domain wide cookie in case you have diff tomcats using diff subdomain. I think newer tomcat may support this as an attribute already but we couldnt upgrade to new tomcat in this short timeframe.

What a rocky start to labor day weekend

Woke up by earthquake at 7:00 AM in morning and then couldn't get to sleep. I took a bath, made my tea and started checking emails and saw that after last night deployment three storage node out of 100s of nodes were running into Full GC. What was special about the 3 nodes was that each one was in a different Data centre but it was named same app02.  This got me curious I asked the node to be taken out of rotation and take a heap dump.  Yesterday night a new release has happened and I had upgraded spymemcached library version as new relic now natively supports instrumentation on it so it was a suspect. And the hunch was a bullseye, the heap dump clearly showed it taking 1.3G and full GCs were taking 6 sec but not claiming anything.



I have a quartz job in each jvm that takes a thread dump every 5 minutes and saves last 300 of them, checking few of them quickly showed a common thread among all 3 data centres. It seems there was a long running job that was trying to replicate pending…

Email slavery

It seems I have become an EmailSlave. The first half of the day is spent in just answering to emails. There are so many emails where I am copied but I need not be. There are many emails  where its a 1-2 page email and somewhere down someone says @KP please answer this.  So it seems daily my work schedule is:
Signin to newrelic and check anomalies for 15 min. Check emails related production exception report and yes there are a ton of these report daily. Need a better tool here as this model is not scalable. I need to reduce the incoming data at me to only see relevant data like what newrelic does. May be I need to create a webapp out of these emails.Check emails for next few minutes before team callsDo team callsThen again back to checking emails until a I have taken a best shot at answering everyone waiting for my reply.Attend team meetings on Tue/Thu
Being an architect and coder at heart I don't feel satisfied at end of the day if there is nothing tangible getting done at the end.…
