Netscaler Knowledgebase

Hi,

I have an internal website that I can't modify and need to publish it as bookmark on the csg clientless webpage.

Netscaler is taking charge of mostly everything but this kind of path is not encoded :

<input type="hidden" value="/RelativeToken/Path/To/A/File.extension">

From what I see it uses a weird javascript that load files thru hidden values inside the html body

So when the browser tries : https://netscaler/RelativeToken/Path/To/A/File.extension it fails obviously because the url has not been encoded and it's not hosted on the netscaler.

I'm quite new to netscaler but, from what I understand, I have several options :
1- Change the default policy to take charge of this
2- Use the rewrite module in order to encode the url
3 - Use the Url transformation so that https://netscaler/RelativeToken/Path/To/A/File.ext will work

I think that the most safe and clean is to use the rewrite module.

However how shall I do to make netscaler encode the url inside the value of an input element inside the body of the webpage ?

I've tried to :
- add an action of type clientless_vpn_encode_all with a http response body caseless regex like this : re~/relativetoken/.*\.[a-z]{3}~
- add a policy always true
- Bind them

But it seem that netscaler reject the binding due to the clientless_vpn_encode_all or clientless_vpn_encode method ...

Someone can help me ?

Best regards.


For the note :
- I use netscaler 9.2
- The local webserver is in Domino 8.0 witch I can't touch

but how to replace an url like this :

/RelativeToken/Path/To/A/File.extension

to this :

/cvpn/hash/RelativeToken/Path/To/A/File.extension

?

By the way, what kind of hash or encoding netscaler is using ?
