I'm currently experiencing problems with static content - most noticeably jQuery datepicker images, but also other static files - which results in images/static content loaded many times - I can clearly see it in IE6 status bar (not to mention SLOW rendering).
The problem and possible solutions seems to be described here: http://www.explainth.at/en/tricks/flickfix.shtml. However, I use IIS6 not Apache, and static files that I don't want to feed through php or asp.
How do I make IE6 cache static images properly? How do I add custom response header for specific files/folders?
Hm, let met re-phrase it. I'm not sure it is caused by the bugs above. Actually, I tried appcmd to apply cacheControlMode/etc and it doesn't seem to work. As far as I remember, IE6 also does not cache for XMLHttpRequest calls? So, the biggest problem that I need to solve is:
in jQuery calendar, moving mouse over image buttons (prev/next) causes them to be reloaded-refreshed
in jQuery dialog, each dialog('open') causes images from theme (like header background) to be re-loaded/refreshed
etc
This link probably gives a better explanation: http://ajaxian.com/archives/internet-explorer-and-ajax-image-caching-woes
How do I solve this - that is, without feeding images through ASP.NET to setup headers?
Thanks everybody for listening, the trick with appcmd seems to work ;-) The problem was that I used jQuery theme from googleapis... which obviously was not affected by appcmd ;-) Moving theme to local folder did the trick. These are the commands:
\Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/images" -section:system.webServer/staticContent -clientCache.cacheControlMode:UseMaxAge
\Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/images" -section:system.webServer/staticContent -clientCache.cacheControlMaxAge:"01:00:00"

I have a problem with an ActiveX webbrowser control, ProgID="shell.explorer.2" in a VB.Net addin development to work within SAP Business 1 running 32 bit on a 64 bit server. It's set to display pages from localhost:1234 which is an OWIN SelfHosted WebAPI. The pages in the site use AngularJS.
The problem is well known on SO, and the FEATURE_BROWSER_EMULATION update does work for me, but I need to find another solution. Since I'm writing an Addin, and the hosting EXE is actually "SAP Business One.exe", adding a registry key changes the setup of every Webbrowser control in the application, whether they're mine, part of the application, or even part of someone else's addin.
Since my Angularjs app seems to be happy with IE10, and I want to set the requirement level as low as possible, I want to ask for IE10 rendering.
The doctype has always been <!DOCTYPE html>.
I've tried a <meta http-equiv="x-ua-compatible" content="IE=IE10"> - even right at the top of the <head> and the mode won't switch.
I've added X-UA-Compatible: IE=10 to the response headers at the server-end for .htm files - I can clearly see the header in Fiddler, and the rendering mode won't change.
So my request for help is many fold - can somebody help with the following:
1) Why don't the X-UA-Compatible headers work in either meta form or as a server header which I thought was supposed to override intranet settings? What am I doing wrong?
2) Is there any way to set the rendering mode via a property or method of an activex interface of the webbrowser control, even if I have to resort to C++?
3) Is there any way to wrap the control in such a manner that the advertised owning process is different i.e. matches myaddin.exe name instead of the main application?
I really would like to get this mode switch working, otherwise I may have to rewrite using IE7 compatible code, which I really don't want to have to do!
Thanks in advance for any help,

I'm including a partial view in one of the pages of my MVC4 site which when deployed, even after a restart of the web site and recycling of the app pool, never seems to affect the site
I'm wondering if this is caching coming into play
I ended up including the content of the partial view in the page iteself and that seems to have worked but I'd rather have the partial view as I'd like to use the view in other parts of the site
The question is, does anyone have any suggestions as to why this might be happening? I've been pulling my hair out trying to get a view to post the correct data, only to realise that some of the hidden inputs are just missing because the partial view has not been refreshed
EDIT:
Ok now I have a need to use this partial view in more than once place. On my dev environment the partial is rendering correctly. Uploading to the server doesn't seem to have any effect, but what's worse, deleting the partial view from the server also has the same issue.
My site still thinks the file is there and complains about the model type passed to the view now (I changed the model type in the view - all working fine on my local dev) - why does it still think the file is there?
I deleted one of the parent views to see if the site carried on working, but as soon as I delete any other file, the site is affected. Why is this particular file giving me trouble? It's as if the server has cached it at the file system level and is supplying the wrong file content to ASP.NET
I'm going to try renaming the file next
Ok so renaming the file appears to have worked.
I didn't try Fals suggestion but I might try that next time, strange behaviour I'm not going to try and understand why at this point!
mod_ajax_dock cart Not working in which come following error.
this.load undefined or can not Cannot read property 'style'.
so plz help me solve this question
That's generally a Javascript conflict caused by the various scripts that your site is loading. The first place to start is to install jQuery Easy to strip out multiple instances of jQuery as well as the usually loaded Mootools. You will have to mess around with the settings, I usually have it strip everything out and see what breaks, then start adding scripts back in until everything works.

I have a very strange problem. I've recently added MVC4 to an old Web Forms project. I did this by creating a new project, and adding the old files to the new project (rather than opposite approach of copying the new MVC files in). When I did this, one of my Web Forms pages stopped working - When I try to access it, it redirects to HTTP Error 404.0 - Not Found.
The file is there, and I also have other Web Forms (.aspx) pages that load without any issues. To pin-point the issue, I created a Web Forms page with the same name to replace it, and it the blank page loads. I started adding code to the new page one line at a time till I found the issue.
I finally found that what caused the issue is when I have more than one RequiredFieldValidator tag on the page. Any idea why this would happen or what I can do to work around it?
assign groups to the validators. Put them in separate groups, dont put them in same groups , make sure You dont have controltoassign be same because then during compilation same requiredfield validator might have concurrency issues and crash the page. Putting them in different groups assures that even more. If you still get the same issue then try this as well
Open IIS Manager
Right Click the server name
Select properties
Click the MIME Types button
Click New

Thanks to everyone in advance -
So I have been banging on this issue for quite a while now and have burned through all my options. My current approach to canceling css requests is with nsIRequest.cancel inside of nsIWebProgressListener.onStateChange. This works most of the time, except when things are a little laggy a few will slip through and jump out of the loadgroup before I can get to them. This is obviously a dirty solution.
I have read through the following links to try and get a better idea of how to disable css before a nsIRequest is created...no dice.
https://developer.mozilla.org/en/Document_Loading_-_From_Load_Start_to_Finding_a_Handler
https://developer.mozilla.org/en/The_life_of_an_HTML_HTTP_request
https://developer.mozilla.org/en/Bird's_Eye_View_of_the_Mozilla_Framework
How do I disable css via presentation objects/interfaces? Is this possible? Inside of nsIDocShell there are a few attributes that kind of imply you can disable css via the browsers docshell - allowPlugins, allowJavascript, allowMetaRedirects, allowSubframes, allowImages.
Any suggestions?
Thanks,
Sam
The menu option that disables style sheets uses a function
setStyleDisabled(true)
so you probably can just call this function whenever new browser tab is created. Style sheets are still requested from server, but not applied. This function is not very sophisticated and doesn't mess with nsIRequest, source:
function setStyleDisabled(disabled) {
getMarkupDocumentViewer().authorStyleDisabled = disabled;
}
Digging in Web Developer Toolbar source code I have noticed that their "disable stylesheets" function loops trough all document.styleSheets and sets the disabled property to true, like:
/* if DOM content is loaded */
var sheets = document.styleSheets;
for(var i in sheets){ sheets[i].disabled = true; }
So if the key is to not apply CSS to pages, one of the above solutions should work. But if you really need to stop style sheets from being downloaded from servers, I'm affraid nsIRequest interception is your only option.
Set permissions.default.stylesheet to 2 and voilà!
You can actually use the permissions manager to block or allow stylesheets on a host-by-host basis.
Unfortunately there doesn't seem to be a simple flag like allowImages. The bugzilla adding for that is https://bugzilla.mozilla.org/show_bug.cgi?id=340746. You can now vote for it using the new bugzilla voting functionality. You can also add yourself to the CC list to be notified if anyone ever works on it.
A related request is to just give us basic HTML parsing support, which may be what you are trying to do. Unfortunately that isn't supported yet either, but you can vote/track the bugzilla for that at https://bugzilla.mozilla.org/show_bug.cgi?id=102699.
So the only workable solution seems to be some sort of interception as #pawal suggests. Here is a link that talks about the basics of interception to at least get you/us started https://developer.mozilla.org/en/XUL_School/Intercepting_Page_Loads. It lists several options that I list below.
These first few seem to just be at the page/document level so I don't think they help:
Load Events (addEventListener load)
Web Progress Listeners (nsIWebProgressListener) - I tried this approach, it only seems to be called for the page itself, not for content within the page.
Document Loader Service - A global version of nsIWebProgressListener so I think it has the same problem (page level only)
That leaves two others I have not tried yet. They work globally so you would need to filter them to just the browser/pages you care about.
HTTP Observers - Seems like it might work, need to verify it calls back for CSS
Content Policy - Seems like the best option to me since it explicitly is called for CSS, someday I hope to try it :)
