Firefox adding no-cache headers to all http POSTs?

Our server-side cache is configured to invalidate appropriate cached data on PUT/POST/DELETE, but is also set to obey no-cache headers and ignore the cache entirely.
Firefox is the only browser that is forcefully appending no-cache headers to all POST requests, resulting in the cache not invalidating properly. Is there some standard that suggests a POST should include no-cache directives, or is this something I can't work around?

Reload the webpage while bypassing the cache using '''one''' of the following steps:
*Hold down the ''Shift'' key and click the ''Reload'' button with a left click.
OR
*Press ''Ctrl'' + ''F5'' or ''Ctrl'' + ''Shift'' + ''R'' (Windows and Linux)
*Press ''Command'' + ''Shift'' + ''R'' (Mac)
Let us know if this solves the issues you are having.

Why doesn't Firefox display all photos posted on Facebook?

Firefox will display some, but not all, photos posted by my friends on Facebook. IE8 displays them all. Do I need to reconfigure FireFox settings to see all photos posted on Facebook?

Thanks. "*Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key). " fixed the problem.

Javier,
I would suggest you to start with something basic and than add complexity.
Create a very simple content rule with just an ip address. no port. no protocol.
Then add one or more servers.
Activate.
Give it a try like this.
Does it work ?
If yes, define 'protocol tcp' and 'port 80'.
Does it work ?
If yes, configure 'url "/*"'
does it work ?
If yes, configure 'advanced-balance arrowpointcookie'
This config is explained at
http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_tech_note09186a0080094398.shtml
It it does not work, tell us what is not working.
Is it the stickyness that does not work or you can't even connect to the vip address ?
Also collect a sniffer trace on client and server.
Thanks,
Gilles.

HTTP authentication key for hand shake at receiver side for HTTP POST

Hi All,
HTTP post receiver system is expecting an authentication key to be send by PI HTTP_AAE adapter while posting XML message to them.
The receiver system has a utility program in JAVA to validate this key. Has anyone done this kind of scenario in PI 7.31/7.4
How does this simple authentication mechanism works? If this doesn't work, we have to rely on just uname/pwd but that is not really recommended for our landscape because of security concerns. So the key is the only better option as of now. Please help!!
thx
mike
Attached some import packages used in the java util program in the receiver system. for validating the authentication key send by PI
import java.security.MessageDigest;
import java.util.Calendar;
import java.security.NoSuchAlgorithmException;
import java.io.UnsupportedEncodingException;
import java.io.IOException;
import sun.misc.BASE64Encoder;
import sun.misc.BASE64Decoder;
I am not pasting the java program utility here due to proprietary reasons. thx for understanding

Hi Michael
You can construct the target URL to include the query parameter/value using Dynamic Configuration in Message Mapping.
This previously worked on the ABAP HTTP adapter, but from the thread below it seems it is not supported on the HTTP_AAE. Not sure what version you are on, and if SAP has provided support for this in the latest SPs.
HTTP_AAE Adapater - using of dynamic url parame... | SCN
If HTTP_AAE approach can't work for you, you can use the SOAP adapter - check ASMA and "Do not use SOAP envelope"
Here is a snippet of the code you can use in a UDF for your message mapping
   //write your code here
DynamicConfiguration conf = (DynamicConfiguration)container
    .getTransformationParameters()
    .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/SOAP", "TServerLocation");
String url = "http://local.yahooapis.com/MapsService/V1/mapImage?appid=" + appid + "--&street=" + street + "&city=" + city + "&zip=" + zip;
conf.put(key, url);
return appid;

[WLS 10.3]:Weblogic.cache.filter does not cache all http headers

When using Weblogic CacheFilter servlet filter to speed our request. However, cached pages miss
some HTTP Headers ie: Content-Encoding.
As a result, if we setup a GZIP filter on most popular static text oriented document like css, html, js, the GZIP filter add a Content-Encoding http header set to gzip. But as CacheFilter forget that header, client receives the correct content-type but not anymore the Content-encoding.
Steps to Reproduce
Ask a static file like a .js library and sniff the HTTP headers. Switch the servlet filter order between gzip and CacheFilter, the HTTP header is correctly set but not when putting cache filter first.

FireFox 7 does not obey no-cache headers?

When I ever I visit my site that sends no-cache headers, FireFox still caches it. It's really annoying in the Admin CP for my forums as it "seems" to make the settings go back, and the success message is not shown. It worked fine with FireFox 6.

Have the same problem with my servlet.
Using these headers:
resp.setHeader("Cache-Control","no-cache, no-store"); //HTTP 1.1
resp.setHeader("Pragma","no-cache"); //HTTP 1.0
resp.setDateHeader ("Expires", 0); //prevents caching at the proxy server
Getting no love from FF7. No problems with FF 3.6, Safari 5, or Chrome 13 & 15.

Adding headers to all mails with spamassassin

hi!
i've followed this instructions: http://docs.sun.com/source/819-0105/anti-spam.html#wp45386
to configure spasassassin and is working fine.
i want to know the score for all my mails not only the ones detected as spam so i want to enable headers for all mails.
is there a way to do it?
regards

Hi,
Unfortunately due to a limit in the size of the argument to the spamfilter1_string_action parameter the sieve filter that does the heavy lifting has been moved to a channel level sieve.
So to discard the email over 10, tag emails below 10 (ham & spam) and file emails from 5-10 into a spam folder you need to do the following:
Replace the previous spamfilter1_string_action with:
spamfilter1_string_action=data:, require ["addheader","spamtest"]; \
spamadjust "$U"; addheader "Spam-test: $U"
Create a file called spamassassin.filter in your msg_base/config/ directory and add the following:
require ["spamtest","relational","comparator-i;ascii-numeric","fileinto"];
if spamtest :value "ge" :comparator "i;ascii-numeric" "10" {discard;}
elsif spamtest :value "ge" :comparator "i;ascii-numeric" "5" {fileinto "spam";}
else {keep;}
Add the following in your imta.cnf file to the ims-ms channel definition:
destinationfilter file:IMTA_TABLE:spamassassin.filter
do you add the spam header on ham too?Yes. ALL scanned emails gets a header added - no harm really.
how do you deal with spam in general?At my previous employee we did what was listed above. Discard spam > 10, tag all emails with the score and filter emails into a spam folder for those emails between 5 and 10 (actually this was customisable/user but that means having a different sieve filter/user and you need to write a custom admin interface for that - most users used the default level to filter into a spam folder).
Also make sure you write an expiry rule for the spam folder so that the spam emails don't build up and consume a users quota e.g. expire emails in the spam folder greater then 30 days.
Regards,
Shane.

How to prevent the Firefox cache from clearing -- all settings are right, but the cache is gone after each restart.

I want to prevent cache from being deleted after each restart. "Clear history when Firefox closes" is unchecked. User.js files are deleted. Checking "Override automatic cache management" made Cache folder appear in addition to Cache2. After exiting Cache is still there, but upon Firefox re-launching, Cache turns into Cache.Trash and promptly disappears. What to do?

Hello,
I'm sorry to hear that. Can you please try these solution to address your concern.
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from [https://www.mozilla.org mozilla.org] (or choose the download for your operating system and language from [https://www.mozilla.org/firefox/all/ this page]) and save the setup file to your computer.
#After the download finishes, close all Firefox windows (or open the Firefox menu [[Image:New Fx Menu]] and click the close button [[Image:Close 29]]).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
<b>WARNING:</b> Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be easily recovered unless they have been backed up to an external device!</u> See [[Back up and restore information in Firefox profiles]]. 
Please report back to say if this helped you!
Thank you.

HTTP caching headers - WL6

I'm evaluating using WL6 as my Web server but can't find a way to specify
what caching headers should be sent with html files. I would like to be able
to specify an expiration for the html files so client browsers will pickup
future updates instead of pulling from non-expiring cache.

Where does firefox cache the form parameters to be used in the reload event of a page that was the resposne of a HTTP POST request?

Suppose there is form in a web page and it submits data in HTTP POST method. After submitting the form, if I reload the page [either by the refresh button or back button; whichever applicable], firefox asks permission to resend the form data by saying "To display this page, Firefox must send information that will repeat any action...". Now if the user clicks on the resend, firefox resubmits the form data.
So where does firefox store this from data for such future resending/resubmission?
Is it possible to retrieve/manipulate those stored form data?

I thought I'd tried that, as tried lots of other things like encoding URL, but obviously not as this works.
Thanks for the quick reply.

Firefox won't load web pages all the way, what can I do to fix this

I have this problem where firefox won't load any webpages all the way and if I try refreshing the page it shows some of the webpage but not the whole thing....and now it won't load any images either. I have tried everything that i could think of and nothing works. I can't watch anything on youtube or go on facebook and google won't work either.

There seems to be something of a pattern in that those are all secure sites (HTTPS address). Have you noticed any certificate errors recently that you might have solved by adding an exception, or does everything seem normal otherwise?
Here are the usual things:
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
"3-bar" menu button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
* right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
In the dialog that opens, you can remove the site's cookies individually.
Then try reloading the page. Does that help?
In case one of your extensions is involved, could you test the page in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?

Is it possible to remember one website in the cache and dlete all the rest of the cache?

I use a program called Visible Body, which takes time load if it is not already cached. I would like to be able to keep it cached, but delte all the rest of the cache. Is this possible?
Thank you

Did you try a new profile?
Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
*http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 23: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

The Firefox window doesn't open at all I can't run safe mode or make other trubleshot changes

since yesterday 08/10/2011 the Firefox window doesn't open at all I can't run safe mode or make other trubleshot changes. When I click on the desktop short-cut the Firefox windows starts loading but before open is crushing.I have sent several messages to you but no answer and my Firfox is not working.

Firefox update failed, so I re-installed. Now firefox won't start up at all?

''locking as a duplicate of https://support.mozilla.org/en-US/questions/969557''
So I ran firefox, and it was updating. While updating, firefox crashed for no apparent reason so I had to close it. Afterwards, every time I tried to start up firefox, it gave me the update failed error, followed by a crash less than a second later. I followed some instructions, uninstalling and re-installing firefox (without removing personal data), but now firefox won't start up at all!
Now what?

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
#Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
#In that text field, enter %APPDATA% and press Enter. An explorer window should open.
#From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
#Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
#Open the most recent 5 files with a text editor and copy the IDs.
#Paste each ID with '''bp-''' into the reply window on the forums.
Thanks in advance!
