Issue with the MaxQ proxy

Hi,
 
I am encountering the following issue with the MaxQ HTTP proxy:
When I visit some websites (e.g. www.google.com and www.postbank.nl )
I receive an empty response.
I believe it may have something to do with redirects but not sure.
 
Is this an issue or am I doing something wrong?
 
Best regards,
 
Cor-Paul Bezemer

Hello,

Unfortunately, I don't know... I'm working behind a proxy and I don't know if I can configure a proxy for maxq so that I can get some external URLs...

However, if you have direct connection to the internet and some web sites work and others don't, you have probably found the problem: redirects.
First of all, MaxQ is based on HttpClient (don't know exactly which version), and HttpClient is not able to handle all kinds of redirections (see http://hc.apache.org/httpclient-3.x/redirects.html). Moreover, after a quick overview on MaxQ sources, it seems that redirects are merely disabled anyway.

www.google.com returns a 302 redirect response actually. Does anyone knows the reason why redirects are not enabled in MaxQ?

It happens that we are currently facing this issue in the CLIF project also (also based on HttpClient). So maybe I could help if I find a solution for CLIF.

Best regards,

Hello Cor-Paul,

Thinking again about this issue, MaxQ actually should not follow redirects: it shall (and it does) forward the 302 response to the browser and it is up to the browser to follow the redirect.
I've tested this with a local HTTP server, with a 302 redirect configured on it. It works like a charm with MaxQ. So, I end up in thinking you don't have a direct access to Internet, but through a proxy. In this case, you must configure maxq to set a proxy: uncomment and set these Java properties in file conf/maxq.properties:

remote.proxy.host=proxy
remote.proxy.port=8080

I've tried with both URLs you provided and it perfectly works.

Note: this message is cross-posted to the CLIF mailing list on purpose since this problem might be experienced by some CLIF users wanting to record and replay HTTP sessions through a proxy.

So, I don't know. Then, probably it is a matter of compatibility with the web browser? FYI, I'm using Firefox version 3 (on Linux).

I have the problem with FF 3 and IE 7 on Win XP.
