Are There Any Issues With ASP And Proxy Servers?
Our website works correctly for 99.9% of customers, however we have one set
of customers who access our website from what appears to be a proxy server
of some kind. i.e. The IP address is always the same no matter where the
location of the computer is.
My site is a framed site, and the specific problem is that a list of links
in one frame will not load a page on another frame. I don't believe this is
a browser compatibily problem. (I wont rule it out though). But there are no
problems as far as I can tell on other peoples computers.
My question is....Is there anything special that needs to be done to make
sure a site works through proxy servers, or is this likly to be some other
problem such as an SSL problem (the whole site is under ssl), browser
incompatibility problem, or just downright dodgy programing on my behalf?

We encountered a very strange problem. We host a web site:
www.[our_site].com and a large number of our users belong to an
organization group with central network control and they can only
access our web site through two headquarter proxy servers: x.x.a.7 and
x.x.b.8, which was set in security dept of the group headquarter. The
web site was working fine till recently when those user accessing via
x.x.a.7 all have problem suddently while those accessing via x.x.b.8
have no problem. The users accessing via x.x.a.7 are directed to wrong
page, very slow response, hang on some page or encounter errors, etc.
If they access the same site via another alias, like
www2.[our_site].com which points to the same web server, they will not
have any problem. They do not have problem to access any other web
sites we tried, including our other web sites hosting in the same site,
even the same server. If the users change their ie setting to use other
public proxy server, they will have no problem to access our site.
Strict security policy are applied to the user site, so we cannot ping,
tracert or do any other network testing from user machine. Since user
has no problem to access any other web site, the headquarter security
department wont handle our case and simply think it is our problem.

We have this portal that accesses content from various places on the web. The portal is SSL secured, so any content that is outside the portal and nonsecure is going to cause an nonsecure error prompt in every page within the portal site.
So, we obviously want to get away from these annoying messages. To do it, we've considered a reverse proxy, and even a tool like WGET... but, WGET can't fetch a complex URL... and reverse proxys seem like they might be a serious pain to set up along side our tomcat server

I work in a corporate environment where they have been restricting (preventing) more and more of what we can view on the internet.I think they restrict that through the proxy server... in Internet Explorer, in Internet Options under LAN Settings, we use an automatic configuration script.
Any way... to make a long story short and to be as truthful as possible, I still want to view my fantasy football web sites. My question is, is there a way I could code
something to get around this? For example, I do have space on a server that runs ASP, so could I code something that would allow me to get around this?

I am making a web-based proxy server, and I need to make it so that it can download a webpage, and modify all of the links inside it (so that it can proxyfy all of the links, rather than the browser downloading the files from the original website).
So far the first bit is fine, but I still need to make my script modify all of the links inside the given HTML file. I know I can do it, but it wouldn’t be the most effective way of doing it. Does anyone have any suggestions on how they would search through an HTML script, and locate links?
So far what I am doing is searching for anything that one of these at the beginning of it:
href=
src=
background=
And I am changing the text that comes afterwards (thus modifying the link). But for many reasons, this is a really bad way of doing it.

I wasnt really sure where to put this thread so I have put it in both ASP and DNS forums - i hope this is ok. My problem feels incredibly complicated so Im hoping that someone on one of the forums might know a few things .

Consider the following simple function to get the contents of a remote URL:
Function GetURL(str_URL)
Set obj_XMLHTTP = Server.CreateObject ("MSXML2.ServerXMLHTTP.3.0")
obj_XMLHTTP.Open "GET", str_URL, False, "", ""
obj_XMLHTTP.Send
GetURL = obj_XMLHTTP.ResponseText
Set obj_XMLHTTP = Nothing
End Function
Is there anyway that I can use a remote proxy server to make the request?

I have a proxy on the intranet, I try to send an xml to an external url, in classic asp, using WinHttp.WinHttpRequest.5.1, but I get access denied from proxy for sending the xml and also The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. Code:

I need to display the contents of an external XML/RSS feed in an ASP page. I have found a couple of scripts that seem to do the trick at:
(URL address blocked: See forum rules)
(URL address blocked: See forum rules)/ow.asp?ASP_Based_RSS_Reader
(any good alternatives will be much welcome)
However, my problem is that the ASP page is part of an Intranet site, so it can only access the Internet (in order to fetch the RSS) via a proxy server.
Can somebody tell me how can I modify the above scripts (or any other that does the same) so the IP/port/login/password parameters can be passed along with the feed URL?

What type of servers allow you to use ASP pages? For example, PHP pages
can function in Apache.
Furthermore, what kind of servers allow you to operate ASP and Access
together?

I have many servers which will be reghosted everyday with different OS
(Win2000, Win2003, WinXP...). How could I write the ASP code to get the
information of other servers' OS?
Let say the asp page is hosted on Server A, how can I check the OS version
of Server B and Server C?

We have a web site where the user logs in and a session variable is set,
which allows access to all pages via an include at the top of every page (
if session("LoggedInOK")<>"Yes" etc)
We have some content on another unrelated server in a different domain that
we would like automatic access to, if the login is OK for site 1, without
re-entering a login. Even better would be if some other session variable
data could be transferred at the same time (like username). Navigation would
be via hyperlinks on site 1. Is there a simple way to do this? i.e. has this
wheel already been invented? (Encrypted querystrings? XMLHTTP?)

I have a need to have a web server (windows based) grab files each week from
a linux based server - hosted elsewhere. I cannot use UNC paths.
I want to have a script (.asp/asp.net) on the windows server that I would
provide a list of files to copy. The script would then copy the listed files.
The problem is that the using a filestream and copyto runs into an error
with URI paths.
This will be a substantial amount of data each week. I don't want to copy
it locally and then back up to the windows web server. I want/need the copy
to be directly between the two servers.

Here's the question: Can you use request.form to retrieve variables and values from a form submitted on a foreign server using the post method?
My understanding was that request.form could only retrieve values from the same web server the form was submitted to, using the post method.
I have another web master telling me this is how you pass information securely between "alien" web servers (web servers on different domains, or belonging to different organizations). For the life of me, I can't figure out how this might be done--or what the mechanism is for fetching the correct values from a foreign server!

In the following code when i = 500 the buffer on the server is flushed
to the client. However, because the content that is sent to the browser
contains an html table Internet Explorer does not display the table
until it receives the closing </table> tag.
The question is, am I
correct in saying that the buffer on the server is CLEARED when i =
500? It will be empty for a split second until the loop resumes again.
Am I correct? Code:

At work we have 2 servers in a cluster for our web apps.One problem we have experienced (along with many others!) - is that if a user is logged into one of the applications on server a for example and it goes offline or fails their session is lost also - even though the application becomes available on server b.
I have heard that it is possible to either exchange the sessions between clustered servers or store them in a SQL Server database (probably preferred) so that we could then restore them if such a failure should occur.Can anyone shed any light on this for me? Or give me some URL's to check out and read.Sorry this isn't a 100% pure IIS question - its obviously partly ASP also.

Let me explain how our web site in constructed before getting to my question. We have three web servers that are a mirror of each other. So whenever I make a change to one of our pages, I have to upload to all three servers. My new task (and its a good one) is to create an image upload script that will distribute the file to all three servers.
I already have an upload script that works just fine, however I wanted to see if anyone out there has attempted anything similar to this and what methods they used to achieve their goal.

I have a .asp application lying out on a Windows 2000 server. The problem is it no longer is working. It seems that no .asp files will execute anylonger on this box. I even have a very basic .asp testfile that prints a line off text to the browser, but even these don't run. I got four errors in the event log for each failure. However, the browser displays this (with friendly error messages et to "off"):
Server Application Error
The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for assistance.
The event log errors are :
A COM+ device failed to start
Did not register with DCOM within the timeout.

I am building an web application that will be hosted on load balanced servers
(multiple front and one backen db). The application will have to allow users
to upload files onto the server. For performance reasons, I do not want to
store binary files in the db (cuz there will be frequently retrieved and
stored and many will be within the range of 10 MB - powerpoint slides and pdf
files) so uploaded files will have to stay on the front end web server.
The problem with this approach is that there will have to be some mechanism that
replicates the files automatically among the front end servers. Can someone
shed some light on what the best apporach is to my problem? I am wondering
whether Windows 2000 has such service available to do file replication (if
so, how?)

I'm trying to figure out a quick script that will let me link to a server share where the server could be 1 of a couple of different ones. The share will always be the same, but the server could be any of a list of maybe 5 or so choices as such:
server1share$
server2share$
server3share$
I'd basically like the script to check the different servers until it finds the one where the share exists, then redirect to it. The share will only exist on one server, but which one it is will change.
