Traffic-Server proxy / checkout failure

[Kevin Blaisdell <bl...@yahoo.com>]

I am stuck with a proxy issue, not knowing if it is
proxy configuration or svn limitation or both.  I have
setup the subversion servers file with my proxy info
and that seems to work find since some of my http
requests go through before things break.

When behind the proxy I get;
>svn co http://1.1.1.1/test/inc
svn: RA layer request failed
svn: OPTIONS request failed on '/test/!svn/bc/7/'
svn: The OPTIONS request returned invalid XML in the
response: XML parse error at line 1: no element found.
(/test/!svn/bc/7/)

OR sometimes

C:\working\BofA\App>svn co http://1.1.1.1/test2/
svn: RA layer request failed
svn: OPTIONS request failed on '/!svn/bc/8/'
svn: OPTIONS of '/!svn/bc/8/': Could not read status
line: An established connection was aborted by the
software in your host machine.   (http://1.1.1.1)

It seems to die on the following broken
request/response

OPTIONS http://1.1.1.1/test/!svn/bc/7/ HTTP/1.1
Host: 1.1.1.1
User-Agent: neon/0.23.9 SVN/0.23.0 (r5962)
Connection: TE
TE: trailers
Content-Length: 104
Content-Type: text/xml
Accept-Encoding: gzip
Accept-Encoding: gzip
Proxy-Authorization: Basic 1fJ6aG1qZz1rb1V04jI41Q==
Authorization: Basic a1V2hW36b2V2aW4=

<?xml version="1.0" encoding="utf-8"?><D:options
xmlns:D="DAV:"><D:activity-collection-set/></D:options>

HTTP/1.1 200 Ok
Date: Wed, 21 May 2003 19:08:42 GMT
Via: HTTP/1.1 cache1 (Traffic-Server/4.0.9 [c s f ])
Connection: close
Allow: CONNECT, DELETE, GET, HEAD, OPTIONS, POST,
PURGE, PUT, PUSH, TRACE
Content-Length: 0

The same exact thing works dialed up another network
to avoid the proxy.  So I know this is a proxy
problem, but not sure exactly why it happens.  I was
under the impression Traffic-Server 4.0.x fully
supports DAV (according to webdav.org).  But obviously
the response to my OPTIONS request gets trashed for
some reason (missing stuff from Allow header, missing
content, content-length=0, etc.

If any Proxy/DAV expert out there has ideas on what
causes this I would love to know.

Thanks,
Kevin

These are known bugs in some versions of Traffic-Server. Inktomi 
said they were fixed in later releases of 3.5.7 - I've only 
personally verified them fixed in 5.2.x.  Inktomi claimed 4.0.x 
was "WebDAV-compliant", which is what the webdav.org page is based
on, but if 4.0.9 is screwing up Allow headers then that .x needs
refining.  I'll check with the developer at Inktomi.
