Proxy problem accessing remote site via FPSE with Expression Web 3.0

Question

I have recently installed Expression Web version 3 alongside the previous version 2. Everything seems great, except that when I attempt to browse the remote site via FrontPage Server Extensions my company's proxy server challenges me for a user ID and password. When I enter my domain credentials I get the same popup screen again.

This does not happen with version 2 of Expression Web - I am able to browse and sync with the remote site every time with no problems.

My theory is that the company proxy server is allowing HTTP on port 80 only and that something in the new version of Expression Web is trying to use a non-standard port or protocol for which my domain account does not have permission.

Has anyone else had a similar experience?

Answer 1

The FrontPage server extensions only use port 80, and I can publish via FrontPage server extensions in xWeb 3 without any problems.

Can you bypass the proxy?

Answer 2

No, our firewall blocks all outbound traffic unless it comes via the proxy server.

Answer 3

Using Microsoft's Fiddler tool, I have logged the network traffic when xWeb connects to a server that runs the FrontPage server extensions. The traffic is almost exactly the same for v2 and v3. Here is the terse summary:

GET http://schneegans.de/_vti_inf.html
200 OK

POST http://schneegans.de/_vti_bin/shtml.dll/_vti_rpc
200 OK

POST http://schneegans.de/_vti_bin/_vti_aut/author.dll
401 Access denied

POST http://schneegans.de/_vti_bin/_vti_aut/author.dll
401 Access denied

POST http://schneegans.de/_vti_bin/_vti_aut/author.dll
200 OK

POST http://schneegans.de/_vti_bin/_vti_aut/author.dll
200 OK

I suggest you try this tool as well. Just start Fiddler, then start xWeb and open the remote site, and all traffic should be logged automatically. Maybe we will see an anomaly.

Answer 4

Thanks for your help Christoph.

I have created Fiddler logs for both version 2 and version 3 but I don't know how to interpret the information.

I can't see a way to attach files to this thread. Can I email the logs to you at the address on your web site?

Answer 5

Be careful. These logs probably contain your password. Look for the Authorization: headers and delete all of them before publishing these logs anywhere. A typical header looks as follows:

  Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==

Yes, you can mail the logs to me.

Answer 6

Thanks for the warning. I would like to remove the password before sending you the files but I am not sure how to do this. Any suggestions?

Answer 7

Maybe you should first post the "terse" summary as I did last week. In Fiddler, right-click the list of sessions, select Copy, then Terse Summary. Just post the text here, no passwords are contained in it.

Answer 9

Okay. There is obviously a difference between xWeb 2 and 3, but there is not enough information to determine the cause. In Fiddler, select the relevant sessions, then right-click and choose Save > Selected Sessions > As Text (Headers only). This will create a text file which contains your password. Open the text file and overwrite all lines that start with Authorization. For example, you could write Authorization: Basic *******. You can then mail this file to me.

Answer 10

I have emailed you the files as requested.

Answer 11

I have this problem also.

V2 works

V3 doesnt

V4 doesnt

Hoping for a fix

Answer 12

I am also having similar issues with the Proxy prompting for credentials, which is pretty much making this a showstopper for me. Why is there no spot to input/cache the credentials in SuperPreview?

Answer 13

This question (which is ancient--over 2 years old) is about browsing the remote site using FrontPage server extensions.

Is that really what you are trying to do? In 2011? Eight years after MS announced that they were pulling support for FPSEs?

And why are you talking about SuperPreview? This thread has nothing to do with SuperPreview.

Start your own thread. Don't ressurrect dead threads.

Answer 14

Yes, I'm human, I made a mistake and failed to check the dates, however funnily enough, the forum path, if you bother to check it:

Expression >

Forums Home>           

Expression Studio Forums>           

Expression Web and SuperPreview>           

Proxy problem accessing remote site via FPSE with Expression Web 3.0

....is why I posted something about SuperPreview here - the problems being experienced although not related to the FPSE specific issue were directly related to the way it interacts with proxies.

...And if it's such a big deal replying to old threads, why did you even bother to comment, especially when you clearly weren't interested in being of assistance.

PS: I'm aware your reply was a year ago.... I thought I'd be consistent. :)

Answer 15

You were told that the *thread*, not the *forum* was not about SuperPreview, when being told not to dig up an old thread, but to start your own with the specific details of your actual problem.

Answer 16

Firstly, thanks for not being of any assistance at all.

I acknowledged my mistake and my reply was light hearted, hence the, ":)" and for Bill alone, but if you really want to join in and play semantics.

1. SuperPreview is built into Expression Web 3.0

2. The thread is found under a forum titled  "Expression Web AND SuperPreview"

3. There is a blatantly obvious "AND" in the forum title;

4. Ergo; any thread under said title can potentially have something to do with SuperPreview, otherwise why would it be in the path to the thread.

If you want to dig at people for where they place things, maybe you should also be having a dig at the original thread creator for not placing the thread under a forum that has "FPSE" in the title.

....to be clear I'm not actually suggesting you do that, but I thought I'd better make it obvious so no one else gets into trouble from the Forum/thread police.

Answer 17

Forum topics are the general area, thread topics are specific.

If you would like assistance start a thread with your issue. Include details as requested in the FAQ. Do not tag onto a post that is about  a completely different issue.

When in doubt start your own thread.

You completely missed my point.  The FORUM includes SuperPreview.  This THEAD does not.  Please reallize the difference between a forum and a thread under a forum.
