Citrix xen app streaming

I have a web application which doesn't work in windows 7 with ie 8 or above but works in IE 7.
I have a scenario where a partner has a hosted vdi which my users access..partners vdi is in his data centre in city a.My application servers are in my data centre in same city.We will be opening up necessary ports and firewalls as per need.

Suppose my users sit in city b and there is a mpls connectivity between that site and partner data centre,I want to know how I can use citrix xen app to give my web application access to users.
Should I need to only install ie7 in my xen app farm and publish or stream it for accessing from partner vdi?
Is there difference between streaming and publishing or is it same?
What kind of firewall rules should be there so that end user just access web application through the ie7 I have streamed/published using citrix

what about firefox?  

Publishing is exactly that - You publish an application that is installed on a server.
Streaming - Run an application locally that is essentially streamed to the client.

You can however publish a streamed application.  So the app isnt on the server but you can stream it to the server to be executed. The it will present it self as an ica application back to the client.

Streaming executes the application over the network as it is being copied. So it is essentially streamed until it is cached on the client /server.

To set these up you will need a matching windows 7 or 2008 box depending on what you are publishing it too then run the Streaming Profiler to capture the application you want to distribute.  After you capture it, you will save it to the apphub (File share on a file server)

When you set the app up you can tell it to either Stream to client, Streamed if possible, Streamed to server and some others.

In your case I would publish IE 7 if you have the option and your security requirements allow it.  Else you could stream firefox or something. This will take up network bandwidth for the initial streaming though.

Just some thoughts..

Thx for reply Casey..we don't use Firefox in our organization..clear about streaming and publishing..but can u advise how things will work in my scenario..vdi is hosted by your company and my users log into your domain using credentials the on vdi they need to see an ie7 shortcut streamed one..and this is coming from xenapp in my datacentre..on opening ie they need to punch a URL of an application say x which is again residing on separate app servers in my dc...is it possible how..what network trust or firewall openings need to be done
OK so your people log into VDI that someone else is hosting and they open Xenapp in your DC? How come you arent publishing a desktop or hosting the VDI there in your DC?
Also there are some GPO settings to tell ie 8 to run in windows 7 compatibility mode.

Its part of a business tieup with 3rd party wer logging to partner vdi..we dont wan manage desktops...even if its ie8 compatible I wanna know how stream works in this model..should weonly need to install ie in xenapp farm and stream and publish it to partner vdi..wat firewall rules need to be open if users punch in an aapplication url in that ie..applcn is in our dc
If you are publishing IE 7, you will have to run that off of 2003 servers in a Xenapp 5? farm.

If you have it behind netscalers you will only need to open port 443 with an ssl cert on it.  Ultimately the programmers need to make the app compatible with the newer versions of IE. There are plenty of compatibility modes and such for IE 8 and 9 to make most web apps work accordingly.

We have both xenapp 5 farm and xenapp 6.5 on windows 2008r2..Any reason ie7 will not work there when published...when u mean net scalers..do u mean ones in dmz zone for gslb...this particular applcn of ours a siebel one downloads some files/activex controls when we launch URL..and when we click ok to download the ie 8 closes automatically...even after we set the compatibility modes in Internet settings
IE 7 doesnt run on windows server 2008 as far as I know. You would have to publish IE 7 from a 2003 server in a xenapp 5 farm to the VDI desktops. IE 7 runs and is executed on the 2003 server. You just see a remote window that looks like IE is installed on the VDI boxes that is actually being broadcast from the XA 5 farm.

Did you check to see if you allowed the active x control to execute in the VDI farm. You can approve addons via Group policy in the IE portion of group policy.
You may need to add the site to the trusted sites on the VDI computer as well.

Will there be a performance impact when a user access a web application by accessing the application through a streamed Internet explorer
You will be publishing and not streaming. There is minimal impact. Actually with citrix's memory handling and caching it should run faster.  You essentially are launching a minimal GUI with just internet explorer on the remote server.
