500 error in Mono + Apache + ASP.NET

There is ASPX(C#) that was running on IIS. I want to operate this on Mono.

We were able to build the environment and check the operation on xsp4. However, it does not work on Apache.(500 error) Likewise, the URL parameter (http:///Layer/sample.aspx?app=sampleApp) also does not work.

I think that the setting of Apache is bad, but I want advice because I do not know where it is wrong.

# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.

#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so

# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.

# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.

Host ASP.Net C# website to Apache or weblogic

We have a Asp.Net website code behind C# framework 4.0 hosted on IIS 6.2. Now we have been asked to migrate it to either Apache or weblogic server. My question is where can we host our website where minimal changes are needed to host our website. And based on your experience do we need to do any code changes in our web site to make it compatible with Apache or Web logic server. Kindly suggest where should we migrate so that minimal or no code changes needed. and minimal efforts for hosting.

how to redirect url with it’s url parameters to custom page in asp.net

I have one default page as : http://localhost:9909/shrtn.aspx

I have added a rule in web.config (default web page rule) using which if i enters http://localhost:9909/ it redirects to http://localhost:9909/shrtn.aspx

rule is as follows :

    <defaultDocument>
       <files>
          <add value="shrtn.aspx" />
       </files>
    </defaultDocument>

But If enter http://localhost:9909/abcdef it throws 404 error page. Is there any way by which i can redirect following url : http://localhost:9909/abcdef to http://localhost:9909/shrtn.aspx

Also i need to transfer parameters, i.e. if i hit url : http://localhost:9909/abcdef , it should redirect to http://localhost:9909/shrtn.aspx?abcdef.

is there any way to implement this??

Rename product page with web.config

Since I have this URL:

http://namedomain.com/product.asp?id=01&color=05&name=xxxx

What is the better approach to rewrite this URL like this:

http://namedomain.com/xxxx

With IIS I was able to generate this URL

http://namedomain.com/01/05/xxxx

This is the web.config code:

<rule name="RedirecionaPagProduto" stopProcessing="true">
    <match url="^exibe_produtos\.asp$" />
    <conditions>
        <add input="{REQUEST_METHOD}" pattern="^POST$" negate="true" />
        <add input="{QUERY_STRING}" pattern="^produto=([^=&amp;]+)&amp;cor=([^=&amp;]+)&amp;url=([^=&amp;]+)$" />
    </conditions>
    <action type="Redirect" url="{C:1}/{C:2}/{C:3}" appendQueryString="false" />
</rule>
<rule name="RenamePagProduto" stopProcessing="true">
    <match url="^([^/]+)/([^/]+)/([^/]+)/?$" />
    <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
    </conditions>
    <action type="Rewrite" url="exibe_produtos.asp?produto={R:1}&amp;cor={R:2}&amp;url={R:2}" />
</rule>

Anyone can help?

301 Permanent Redirection, Urls are not changing

I am implementing 301 redirection, but the problem that I am facing is, the urls are not changing, and when I implements 302 url start changing, is their any way through which I will implement 301 and the urls will change as per the need.

Like: www.abc.com and abc.com. I need only one URL to display in my browser when I hit anyone of the above mentioned URLs.

Thank you!!

Apache2 ASP MVC Razor view crashes when referencing PCL enum for dropdown

I am new to using ASP.net on ubuntu with mono, I have several websites working very well indeed using MVC5, though I recently migrated a project over and have found that forms referencing enums from a referenced PCL cause views to crash. Below is my EnumDropDownList call which works fine on a windows host.

<div class="form-group">
@Html.LabelFor(m => m.Type, new { @class = "control-label" })
@Html.EnumDropDownListFor(m => m.Type, new { @class = "form-control" })
</div>

When viewing this in the browser on the ubuntu host however I get the following error

System.InvalidOperationException
The view found at '~/Views/portal/productgroup.cshtml' was not created.

Additional the stack trace is

     at System.Web.Mvc.BuildManagerCompiledView.Render (System.Web.Mvc.ViewContext viewContext, System.IO.TextWriter writer) [0x00061] in <cc73190bab9d435c831510ff295c572a>:0

Is there a way I need to reference the external assembly in my controller or my razor view? Is this a common issue or could there be something specific going on?

For reference the PCL holds some shared code for use between my site and a mobile app built using Xamarin. The PCL has the profile .NET framework 4.5 in addition to all of the Xamarin ones etc. The code is fully operational on windows and will work if I remove references to the enum stored in the PCL.

Any help would be greatly appreciated.

asp.net server redirect causing Not Found [CFN #0005]

So I've built a very small form website using asp.net and visual studio express 2015. The site works fine locally so far - but when I push everything to the hosted site it doesn't work.

The issue I currently have is the page is redirecting to a non-file extension page which results in the Not Found [CFN #0005] error message. So when going to www.mysiteexample.com/mainpage.aspx in the browser it is redirecting to www.mysiteexample.com/mainpage - and since there is no file named just 'mainpage' it is returning the not found error.

I've looked in a lot of places to try to find out why this is an issue - are there rewrite rules to put in web.config? Nothing seems to have worked. Should there be entries in the .htaccess file? Does there need to be some kind of configuration change on the server - which would require the hosting company to make? (by the way, the hosting company is saying its strictly a code issue and won't help).
