#1856: LostHeader with regsub
------------------------+---------------------
Reporter: gdelacroix | Type: defect
Status: new | Priority: normal
Milestone: | Component: regress
Version: 4.1.1 | Severity: normal
Keywords: |
------------------------+---------------------
With 4.1.1, I get a "LostHeader req.url" and "Error
workspace_client overflow" when using this line:

set req.url = regsub(req.url, "/([?])?$", "\1");

...that I took there a while ago: https://www.varnish-
cache.org/trac/wiki/VCLExampleNormalizingReqUrl

I didn't get this issue with 4.0.3

The issue occurs because the regsub actually removes the url when it's
just "/".

Adding 'if (req.url != "/")...' or changing the regexp by "(?<=.)/([?])?$"
to check there's something before the removed slash fixes the issue but
the fact this error appears in 4.1.1 and not in 4.0.3 (didn't check 4.1.0)
maybe an unexpected behavior...

Anyway, the wiki page should be fixed ;o)
