Preparing Citrix NetScaler 11 integrated Caching for Front End Optimization

Front End Optimization on a Citrix NetScaler will only work, if caching is set up correctly. This is especially true for image optimization. Usually it’s caching to blame for if image optimization does not work. So what to do? Citrix tells us (edocs.citrix.com): Front end optimization requires the NetScaler integrated… Read more »

Making a NetScaler Gateway on NetScaler 11 a bit more secure

last update February 7th 2017 We have previously created a NetScaler Gateway on our NetScaler 11. That’s great! Time to check if it’s secure. I usually use SSL labs SSL test, a widely used tool to test the security of a website. I have an other blog about NetScaler virtual… Read more »

Setting up a NetScaler Gateway on NetScaler 11

It is quite easy to set up a NetScaler Gateway on NetScaler 11. It’s quite similar to NetScaler 10.5, but the wizard is much more powerful now! I’ll show you how to do it. Prerequisites I assume you have: a certificate in place. This certificate should be a valid certificate created… Read more »

There are 2 reasons for this: Badshop uses a java script to forward users to http://www.badshop.net/cgi-bin/badstore.cgi. So it will forward… Read more »

Installing Badstore.net on a XenServer

UNSUPPORTED_INSTAL_METHOD I asked Google and found a solution: find the UUID of this machine. It’s listed on the General… Read more »

Automatically forward users of a loadbalanced StoreFront server to /Citrix/StoreWeb

This question was asked by one of my students during one of my last NetScaler CNS 207 classes. It should not be a difficult problem. So what do we need to do? rewrite requests to /Citrix/StoreWeb. filter on requests without URL specified. bind it to the load balancing server. (there… Read more »
