iwproxy remap problem

frogman

Hi,

I am having troubles with iwproxy_preconnect_remap.

Platform: TS 6.1 on a Win 2003 Standard 32 bit box.

We have a seperate app server that lives in a different domain from the TS box and is running CF MX6 on Windows 2000.

I cannot get remapping to work with the remote server.

For testing, I have set up the iwproxy thus:

##############################################################################################
# Double Proxy
#--------------------------------------------------
# 2nd pass -- catch the /iw-mount/double_proxy path
#--------------------------------------------------
# (note that the rule for the 2nd pass MUST come first)
#--------------------------------------------------
_regex=/iw-mount/double_proxy/(.*)=http://dev.appserver.com.au/$1
#
#--------------------------------------------------
# 1st pass
#--------------------------------------------------
_regex=/iw-mount/default/(.*)$=http://localhost:1080/iw-mount/double_proxy/default/$1
#
##############################################################################################
Please note: I have replaced the client's URL with "dev.appserver.com.au" for client privacy reasons.

Trying to preview "test.htm" from Teamsite.
Using iwproxy -d I have confirmed that iwproxy correctly builds the remap path to http://dev.appserver.com.au/test.htm.
However, the page will not render (I get an "HTTP 500 - Internal server error" in the browser). iwproxy reports that the "url does not parse"

I have checked the IIS site on the app server, and everything is correct.

What is weird is that if I paste "http://dev.appserver.com.au/test.htm" directly into the browser it works fine.

Can anybody advise?

AAHGA.

Thanks
Frogman

have you configured your CF server to have its doc root mapped to the appropriate area on the y: drive?

for test, I'd type the URL that you think is correct, directly in the browser window. If your CF settings are correct, it would display the page.

Hi Greg,

As I said in my post, The problm only arises when trying to preview from Teamsite. I have tested by cutting and pasting the correct URL from the iwproxy debugging info, and also by typing it manually, into the browser address bar. In both those cases, .HTM and .ASP files render fine. I get a CF styled - 404 for .CFM files. I'm not too concerned about CFM files until I've got the HTM files working OK using the double proxy. Any ideas?

Cheers
Mike

oops, I missed the second part of your post. you're right...

what do iwproxy's settings say about HTML and ASP files?

Hello again Greg,

I'm not too sure what you mean here. For testing I've set the double proxy to use the remote app server for ALL content - so any HTML, ASP, CFM pages will all get remapped to the remote app server.

Are there some other iwproxy settings I'm missing? I've attached iw.cfg FYI.

Thanks
Mike

well, you had a number of commented-out entries. Your first pass does not seem to be getting out the right result.

as you know, the idea of double proxy is to 1st map the URL to a path that contains some unique name (double_proxy), but still with iw-mount, so SCE is injected, and then pass it to the external server. I can't see that this is happening.

as per plaird suggestions, you should complete 3 steps when debugging double proxy.

I hope you have a nice weather in Perth Smiley Happy

Greg,

The weather here is fantastic (much like Sydney's awesome Autumn weather as I recall from my time Over East - around 28, not a cloud in sight). Unfortunately, I don't get the time to enjoy it due to the complete lack of any meaningful documentation from Interwoven on their own product. I'm really frustrated with this. You'd think it would be a pretty simple and straight forward task to set up a proxy.

Anyway, that's my rant for the day. As you rightly point out, following Plaird's 3 rules for debugging iwproxy, I've had the first of them working for some time. I can browse to the app server with no problem and it will serve any pages if the URL is typed in manually. The issue I have is that if I take the URL as configured by iwproxy and manually enter it into the browser, it works fine. It is ONLY when trying to preview directly from Teamsite that I get a problem. To add to my frustration, the response from iwproxy is a single text line that says "[url does not parse]". But I KNOW this URL DOES work so what is iwproxy actually trying to tell me?

onwards and upwards.....

Mike.

Mike,

as plaird has said - if step 3 does not work, the app server logs need to be inspected - it could be some authentication, a cookie not being sent, etc, etc.
