Proxing name based virtual host

[Sigitas L]

Hello,

I am trying to create a proxy for name based virtual host as described here:

http://open.litespeedtech.com/mediawiki/index.php/Help:Proxying_with_Rewrite_Rules#For_name-based_virtual_hosting

However when I try to access web page browser shows nothing (downloads forever). This happens with 1.4.16 and 1.4.13 versions. With version 1.3.12 I was able to create such setup successfully. 

Maybe something was changed here? Do you have any hints how I could debug this?

Hi Sigitas,

Apologies for the late response, for whatever reason, I did not see the notification for this.

I am able to reproduce the problem, will let you know when I find out more about this issue.

Cheers,

Kevin

Hi Sigitas,

Below is the patch that should resolve the issue. Let me know if it works for you.

If you installed via a package manager, it will be part of 1.4.17.

Cheers,

Kevin

Hello, 

had a quick test on 1.4.14 - it works as expected now.

[Kevin Fwu]

Perfect, thanks for letting me know!
