Web Forms :: No Caching In Google Chrome?

Does anyone know how to prevent caching of ASP.NET pages in Chrome? I tried using the following in the Page_Load event but it does not work:

Response.Cache.SetCacheability(HttpCacheability.NoCache);
//doesn't work in Chrome

Google Chrome Caching DropDownList Selections

May 21, 2010

I'm experiencing what seems to be a caching issue with Google Chrome and Safari on my cart page. In the cart there are 2 dropdown lists. When you hit the checkout button after changing the values in the dropdown lists, it commits what's selected in the lists to the database.

It's a little bit hard to explain the unexpected behavior so I will try to write it out step by step with an illustration of my problem.

Lets say the first dropdown list has the values of:

VALUE1
VALUE2
VALUE3

And the second dropdown list has the values of:

DUMBO1
DUMBO2
DUMBO3

I add an item to my cart.

Screen Says: VALUE1, DUMBO1

Database Says: VALUE1, DUMBO1

I hit Checkout.

Database says: VALUE1, DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page)

I hit the back button.

Screen Says: VALUE1, DUMBO1

Database Says: VALUE1, DUMBO1

I drop down the VALUE1 combo and select VALUE2, VALUE2 is selected momentarily and then the site posts back and VALUE1 is re-selected in the drop down list (from being reloaded from the DB)

MOMENTARILY Screen Says: VALUE2, DUMBO1

Database Says: VALUE1, DUMBO1

THEN AFTER POSTBACK FROM DROPDOWNLIST_SELECTIONCHANGED EVENT

Screen Says: VALUE1, DUMBO1

Database Says: VALUE1, DUMBO1

Hit Checkout.

Database Says VALUE1 ,DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page)

Go back.

Screen Says: VALUE2, DUMBO1

Database Says: VALUE1, DUMBO1

So it appears that it's remembering my selection of VALUE2 even though it jumped back to VALUE1 before I checked out.

It seems to be a caching problem, however I've got some no-cache code to prevent caching of that page that works great in firefox and internet explorer but seems to be failing in Chrome and Safari. I'm basically returning in the headers for the cart page: no-cache, no-store, and must-revalidate to attempt to prevent caching, but based on this scenario it seems to be caching the page anyway and not reloading it when I hit the back button.

Web Forms :: Microsoft WebControls In Google Chrome?

Feb 10, 2011

It looks like WebControls do not work correctly in Google Chrome. I've researched this issue and found solution here but it does not work in my case. Maybe because our server is on .NET 4. Does anybody know how to make WebControls work in Chrome/Safari? Unfortunately changing WebControls to something else currently is not an option so I must find a work-around.

How To Get Chrome To Stop Caching When Working On An Aspx File In Visual Studio

Jan 4, 2011

I'm currently editing some html/css within a aspx file inside of Visual Studio 2010. I'm using Chrome as my browser. When I make changes inside of Visual Studio and save/ctrl + F5 to run it frequently fails to load the new updated .css file due to pulling old cached versions of the CSS.

I've used visual studio as my primary HTML editor before but when I work with pure html/css files I just save and refresh the file in chrome and it will refresh the updated css 100% of the time. I've only started to experience this problem when working with aspx files and running things via ctrl + f5. Anyone have any ideas of how I can fix this?

WebParts And Google Chrome

Oct 4, 2010

I started learning ASP.NET these days. Google Chrome is my default browser and I'm also testing my applications in Google Chrome.

I recognized that some Elements of ASP.NET won't run in real time when I use Chrome. For Example ASP.NET WebParts. If I change the modus of the WebPartManager from default to edit (or something else), Google Chrome needs 1 - 2 seconds to renew the page. Internet Explorer does this in real time without any loading times.

I'm a rookie in ASP.NET and many people said, Microsoft's AJAX for ASP.NET is some kind of crap.
I'm using Visual Studio 2010 and maybe you'll say, I should use jQuery instead of internal Features like WebParts.

Page Loads Twice In Google Chrome

Jan 5, 2010

Does anyone have any problems with Page_Load being executed twice in Google Chrome?
It's a short question, i do not know what else to explain...

I have a simple asp.net page and in Firefox and IE all it's working fine.
But in Chrome the Page_Load is fired twice...

Later EDIT:
- what is strange is that i have 4 repeaters... binded with random values. The random methods are twice fired (because of page loaded twice) but the repeaters takes the INITIALLY values...so, the 2nd post back is somehow raised after the rendering step.

3rd edit: It happens ONLY at the refresh!

Solution (in my case): There was an empty img src, and that was the cause

MVC :: Image Upload Failing In Google Chrome

Feb 10, 2010

I have an image upload form:

[Code]....

That posts back to the action
[Code]....

The code works accross all browsers but Google Chrome. My IDE is Visual Studio 2k8, and I haven't figured out how to debug on Google Chrome with it, however, I am throwing error messages, and I know that for some reason under chrome, the following check doesn't pass:
[Code]....

So apparently, under Chrome, the HttpPostedFileBase parameter picture isn't encoded right and loses its mime type, howwever, this might not be the only problem. What is excatly wrong with the HttpPostedFileBase parameter under Chrome, and how can I fix it?
