I have started having problems with our asp.net webform applications running behind a proxy since the user base have upgraded to IE7. Some postbacks seem to drop out and at times it is difficult to make controls on a page raise an event. It appears to be intermittant and I have been told there are issues around using IE7 behind a proxy with post requests. Is this the case and what are the options? Rewite in MVC? Does the issue of post requests behind a proxy remain in IE8?
I am trying to make a web request programmatically. When i submit the request through the browser it seems to work fine but when i programmatically submit the request it comes back with this error message "Unable to connect to the remote server"
Below is the code i am using to executing the command,
[Code]....
[Code]....
I assume the reason why i am getting the error message is because the proxy server has not been set programmatically. Can somebody tell me how i can get the proxy server and set it programmatically?
I have a website [URL]. Recently I found out that somebody has set up a reverse proxy with an almost identical url "www.website1.com" in front of my website.
I'm concerned of those users who came to my website through that reverse proxy. Their username and passwords might be logged when they login.
Is there a way for me to have my web server refuse reverse proxy?
For example, I've set up a reverse proxy using squid with the url "www.fakestackoverflow.com" in front of "www.stackoverflow.com". So whenever I type "www.fakestackoverflow.com" in my web browser address bar, I'll be redirected to "www.stackoverflow.com" by the reverse proxy. Then I notice the url in my address bar changed to "www.stackoverflow.com" indicating that I'm no longer going through the reverse proxy.
"www.stackoverflow.com" must've detected that I came to the website from another url and then redirected me to the website through the actual url.
In an article I have read "A web browser can be named as proxy server. As safari, chrome, mozilla".But proxy server is like a an intermediatary btween the clent and server know?
our web application should be hosted under proxy server, for that we had to change our URL to be relative.
we changed all the url's but then we saw that web resources that are embeded in the .net dll's are being written to the page with absolute path, start with "/" for example:
[Code]....
how can we change it? how can we set the web resource to be relative like this "../webresource.axd"
Well I would like to get understanding on sql server security. how to map windows user eg:'srm123' to sql server agent so that user when logins in sql server can also work with sql server agent.bydefault u can not see sql server aqent icon in ssms in userlogin.what is a role of a proxy and credentials how to map them with windows user to workwith jobs and alerts.
I am trying to deploy through webmatrix but my system Proxy server configuration is not being used. I assume that webmatrix would detect the proxy server settings and use that for the msdeploy calls under the hood. Can anyone confirm this is a know issue?
The remote server returned an error: (407) Proxy Authentication Required.I get it when I use the GetReponse() method in WebRequest Dim request As WebRequest = WebRequest.Create(getNextURL()) Dim httpResponse As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
the site normally works fine in all popular browsers including firefox, chrome, safari and ie.
but doesn't work in ie 8 when it's redirected via a proxy server and it gives an error saying
"Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

I am guessing it has to do with the size of hidden "__ViewState" tag in my ASP.NET pages.
I also realize that this is restriction imposed to by IT on the users end and I have no contol over it.
I disabled ViewState on all the controls in my ASP.NET pages. However, __ViewState is still generated very large (as always) to persist control-state (e.g. checkbox, radiobutton, etc.)
I am working on a page that has multiple sections and each section looks 'almost the same'. Having said that, I want to build the HTML on the server and render it for each section on the initial page load. On subsequent actions, I would do a ajax call and have the server return json data.
The other option is to 'hardcode' the HTML on the aspx page and have the JS do the necessary customizations for each section. The third option is to use an UpdatePanel and do everything server side.
Based on what should I be choosing what approach to use? What approach would you use for a page like this (think of it as a large page having sub sections on it)
Edit: One section has HTML such as user's name, and a table where users can add dependents. Another section is almost the same except its for a 'contractor' so there's additional HTML such as previous work history, but this one has name (readonly) and a table to add dependents just like the first one. Other sections have more or less the same HTML. A user can delete dependents as well, when that happens, I need to update the database and update the section to reflect one less dependent. I was hoping to make any subsequent actions as ajax calls that interact with the server and the database
I am getting the following error using an update panel with a gridview. Microsoft JScript runtime error:Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.Common causes for this error are when the response is modified by calls to Response.Write(),response filters,HttpModules,or server trace is enabled.
I have looked at all the "fixes" for this and none of them seem to be working.It works just fine on page load but when I click my async button,One row of the grid processes(I can look in the javascript debug) but after the firstrow is processed,I get the above error at this line.
What I do in this code is convert a BLOB value from a database and store it in a string in a custom object.What seems to be happening is that there are odd characters being put at the end of the string.Here is what I am doing to convert the data

It appears in both FF and IE so far, and only happens on the live servers.
It occurs within partial (or attempted partial as they stop working and don't update) postbacks within an update panel on a form that is on every page. It doesn't always do it, but once it's broken, it's consistent. I have a suspicion that it kicks in after the pages in question have been posted back to by another page, but I'm not 100% about this. This form is absolutely integral to the function of the site.
I am getting this ajax timeout error.I am using updatepanel and update progress. Locally am not getting this error but after hosting this error is coming and the page is not navigating to the next page to show the result.
I tried most of the solutions eplained like below,
Am getting this error on clicking any of my page link.

I have the following source code, but it is not working properly. All 3 panels popup OK. but in Panel3 I have a RadioButtonList that changes the date in the BeginDate and EndDate dropdowns.

When I click on continue I get the following error.Microsoft JScript runtime error: ys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

Is it possible to send an e-mail in my Asp.Net application through a Proxy server?
I tried using system.net configuration on my web.config but it seems that it accepts only URL proxies. Here's what I'm using:
[Code]....
I tried to disable the defaultProxy setting but I still couldn't send e-mails. I was able to get a remote web page content through my code using System.Net's WebProxy, WebResponse, WebRequest and NetworkCredential.
Unfortunately, SmtpClient does not provide a Proxy property. Is there any technology available to send e-mails through a proxy server? Currently I'm using .Net Framework 2.0 but if it's possible using 3.0, 3.5, Ajax Extensions or anything like that I'll start using it. But so far I couldn't find anything related to it anywhere.
If it's not possible then I'm gonna have to place a system requirement for a direct connection to the internet... I don't like it very much, but if its not possible....
Is that possible to get the proxy settigns right across several browsers, such as IE, firefox or safari from Asp.net? According to someone it is impossible because ASP.NET runs on the server, and therefore has very limited access to the client's settings.
But having said that, HttpBrowserCapabilities is able to retrieve plenty of information from a client machine, so i thought there is must a way to also retrieve the proxy settings on client's browser/s.
Is there a way to get the precise client's operating system, coz the HttpBrowserCapabilities.Platform property doesn't give me the precise client's operating system.
I tried the below code for getting clinent ip address. Request.UserHostAddress; or
Request.ServerVariables["REMOTE_ADDR"]; or
Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
If the request coming from IE it will work file, but in the case of Mozilla Firefox it shows the proxy ip address. I am getting the sam ip addres from different machine if the request from mozilla firefox.
