iisproxy's Issues

proxy.ashx

I've used your code to build a webhandler (.ashx) that fits my needs perfectly.
I'm searching for a ProxyHost (ForwardProxy) to use with openlayers, as 
documented here: 
http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#ProxyHost

request like '/proxy.ashx?url=localhost:8080/geoserver/wfs' 
are redirected to my intranet server, maintaining POST data.

I add my adapted code as attached.
Thanks a lot

Failed to access IIS metabase

This isn't really an issue. I just ran into the error "Failed to access IIS
metabase" and thought it might be useful to others to know the solution.

Escaped characters in URI get corrupted (i.e. russian words in query parameters)

Query params (GET method) like
?q=%d0%93%d0%b4%d0%b5+%d1%80%d0%be%d0%b4%d0%b8%d0%bb%d1%81%d1%8f+%d0%9f%d1%83%d1
%82%d0%b8%d0%bd%3f

Will be escaped second time and passed to back-end as:
?q=%25u041a%25u0442%25u043e+%25u043f%25u0435%25u0440%25u0432%25u044b%25u0439+%25
u043f%25u0440%25u0435%25u0437%25u0438%25u0434%25u0435%25u043d%25u0442+%25u0420%2
5u043e%25u0441%25u0441%25u0438%25u0438%3f

Request.RawUrl works fine for me:

public void ProcessRequest(HttpContext context)
{
   string remoteUrl = ConfigurationSettings.AppSettings["ProxyUrl"] +
                    context.Request.RawUrl;

username/password dialog produced by browser instead of proxied content

I don't seem to be able to get your version 0.4 of the reverse proxy to 
work. I run a win2k3 server with all latest patches applied, and what 
happens when I follow the readme instructions is I get a username/password 
dialog on trying to connect with the web browser to the URL which should be 
delivering content of the proxied site.

Am I not understanding something properly here? The server is running IIS 
on port 80 as well as a turbogears app on port 8001. I've followed the 
readme in an attempt at setting up http://mysite/TGApp to deliver the 
turbogears site from port 8001. The web.config file thus contains this:
<add key="proxyUrl" value="http://localhost:8001" />

Adding traceRedirect also appears to have no effect, nothing gets written 
to the application log.

Fails on Large File Upload

I have an MVC web app running on Windows Server 2008 R2 IIS 7.5, ASP 4.0 (call 
it machine ‘B’).  A Windows 2003 IIS 6 (machine ‘A’) is running this 
‘IIS Reverse Proxy’ code.  The application works fine via the reverse proxy 
until I try to upload large image files (it works with small ones). It also 
works when I   When I try to upload a large file (6476 KB) the original code 
returns the error “The request was aborted: The request was canceled” on 
the line “output.Write(buffer, 0, read);” in the CopyStream method in 
‘ReverseProxy.cs’.  It appears to start failing on uploads of files greater 
than 4 MB.

When I try the change suggested in Issue 7 (related to “chunking”) the 
error changes to “Could not contact back-end site” (error text is from the 
Process Request method in ReverseProxy.cs).

By the way I also tried increasing the byte[] array in CopyStream but that did 
not help.

In all attempted versions of ReverseProxy.cs I get an error in 100 seconds.  I 
have changed the web.config in both Machine A (hosting ReverseProxy.cs) and 
Machine B (my web app) to include:

  <system.web>
    <httpRuntime maxRequestLength="2097151" executionTimeout="36000"/>

but still fails.

I can’t find any errors in the event logs on either machine related to 
timeout or otherwise.  I assume (maybe incorrectly) the problem has to be 
related to timeout but where/how can I fix it?  Any ideas?   Thanks.

File size seems to cause failed response

What steps will reproduce the problem?
Dynamic pages fail if response exceeds an undetermined size (not very big 
either)

What is the expected output? What do you see instead?
Page contents expected but no response. HTTPFox in FF shows 
NS_ERROR_UNEXPECTED

What version of the product are you using? On what operating system?
v4 on IIS 6.0 retreiving from Apache on XAMPP server.

Please provide any additional information below.

All features seem to work fine. 
Setup was a breeze.
Large .js files have no issue, but text/html files that exceed ~6k simply 
never respond.
Thought it might be a timeout issue or something, but have no idea where 
to look. Have you seen anything like this?

Could not load file or assembly 'ReverseProxy'

I'm getting a configuration error.

I followed the install instructions to the letter, creating a /remotesite
folder where I wish the reverse proxied site to be based, and a
/remotesite/bin subdiretory to install the ReverseProxy code.

However, the installation instructions are somewhat vague, so just to clarify:
In step #3, does "this directory" refer to /remotesite/ or /remotesite/bin?
In step #7, what extension pattern should we use? I assumed we should use .*
In step #10, again what directory does "in the directory" refer to?
