Illegal character in path

We have some problems in a gatling simulation where one of the requests we sends, results in a redirect to a URL containing the following URL-encoded character: %20.

When this redirect occurs, we get the following error in our gatling log:

java.net.URISyntaxException: Illegal character in path at index 37: htttp://www-t3.nav.no/Arbeid/Utlogging Fra Tjenesten

We have tried setting useRawUrl in gatling.conf to true, but with no effect.

Any tips on how to fix this problem?

Do you have an example of the returned "Location" header ?

java.net.URISyntaxException: Illegal character in path at index 37: htttp://www-t3.nav.no/Arbeid/Utlogging Fra Tjenesten

Did you noticed that there is 3 "t" in "htttp" here ?

cheers

Sorry, a typo from me when pasting the error message... The URL and the redirect works in browsers, but when we run a simulation (recorded by Gatling) we get this error.

If the issue is about the white space in your Location header:

Yes, as per RFC, your header is invalid
I've add support for those malformed header in AHC 1.7.15 (https://github.com/AsyncHttpClient/async-http-client/issues/268), which is about to be shipped in Gatling 1.5.0 and 2.0.0-M2 that I'm releasing at this very moment.

Making it short, please wait 30 minutes and stay tuned.

The Location header looks like this:

http://www-t3.nav.no/Arbeid/Utlogging fra tjenesten

The same as the URL printed in the error message.

BTW, if you can get this Location header fixed, you'll do the internet some good (even minor).

Any ideas on why this happens?

One more thing: Seems like the links to the different versions have been mixed up on gatling-tool.org. The link for 1.5.0 points to 2.0.0-M2, and the link for 2.0.0-M2 points to 1.5.0

Thanks! Seems to work fine!

Yep, I just fixed them, thanks!

So you no longer have your weird "Exception in thread "main" java.util.zip.ZipException: ZIP file must have at least one entry"?

No. The weird error got away when installing a fresh copy of Gatling.

But, I was a bit quick on checking our original error. Seems like it's still there in version 1.5.0. I've also set useRawUrls to true in gatling.conf.

Here is the full stack trace. I can't see that AsyncHttpProviderUtils is active in the call stack?

Ah, I see. That's something I didn't backport in Gatling 1. Will do for 1.5.1.

If your willing to migrate to 2.0.0-M2, it should work.

Sounds good!

Looks like we're able to change the Location in the header. Any idea of when 1.5.1 will be released?

Great.

It depends on this issues that might arise in the next days. We tend to release fixes at most every 2 weeks.

Also note that you can grab SNAPSHOTs from our CI: http://repository-gatling.forge.cloudbees.com/snapshot

A 1.5.X build is under way with the backport: https://github.com/excilys/gatling/issues/1138
