irule apology page logo/image not working
I have deployed apololgy pages a bunch of times and never had any issues, but I'm running into one now. The issue is simple, the image isn't displaying, and I can't figure out why. I have a *.htm file that has img src="/apology.jpg" width="737" height="79" alt="" title="" / I then have an irule that says: if {[HTTP::header referer] eq ""} { switch [HTTP::uri] { "/apology.jpg" { HTTP::respond 200 content [ifile get "apology.jpg"] } default { HTTP::respond 200 content [ifile get "access_denied.htm"] } } } } The users gets redirected to the apology page but the logo just shows a big red "x" in it. The strange thing is that if I look at the properties it shows the logo url as And if I navigate to that URL the logo displays just fine...it just doesn't display on the apology page. I've used this exact same logic for numerous apology pages and never had an issue...i'm sure it's something simple that i'm overlooking but i've been overlooking it for two days at this point so any assistance would be appreciated. Thanks in advance235Views0likes1Commentunable to install 2nd image to F5 VE LTM but can not resize disk
I have a VE in AWS with two images on it. When I went to install a third I got this error "failed (Disk full (volume group). See SOL#10636)" I deleted the failed partition and the unused partition and tried again. Still received the same error typing "vgs", shows "vg-db-sda190 wz--n- 99.79g 9.71g"...................9.71G is not enough free space but none seems to have been recovered by deleting the second partition. I tried using this article https://support.f5.com/csp/article/K74200262 to free up some space using "lvreduce --resizefs --size -10G /dev/vg-db-sda/dat.appdata" but that fails with "resize2fs: Inappropriate ioctl for device While trying to add group #4096" so I have a VE with one active partition and no way to apparently load any other images........I have similar images with 3 partitions so I am really unclear what is going on. Seems like deleting volumes/partition did not recover any space. Unit has been reloaded a couple of times. Any help would be appreciated Thanks598Views0likes3CommentsGetting the following error when trying to upgrade device from version 11.4 to 12.0

Hey all, anyone having issues uploading an image for things resource links added to an APM full webtop? On version 12.1 when uploading an image to replace the Globe image, it looks like it wants to use the full file path (i.e. c:/folder/blah/filename.jpeg) instead of what I am used to seeing which is just the file name. Getting an invalid file name error which I am assuming is because of the extra colons and slashes in the file path. Any help appreciated. Thanks.294Views0likes1CommentLTM V10.2 - Splash Page image file
Hi folks! I have a requirement where the BIG-IP LTM has to present the user with a splash page (image file) when all of their servers are offline. Base on some previous dev central threads, looks like it can be done by converting the image file to base64 format and placing this encoded string into a iRule group and then access it using an iRule. I have successfully decoded the base64 string back to the image file using a tool just to verify that the base64 string is valid. Here is how my iRule looks to test out the image file on the browser. when HTTP_REQUEST { HTTP::respond 200 content [b64decode [lindex $::Test_Lab_Splash_Page_Group 0]] "Content-Type" "image/png" } Following is the error that I see in the log file. 01220001:3: TCL error: Test_Lab_Splash_Page - conversion error invoked from within "b64decode [lindex $::Test_Lab_Splash_Page_Group 0]"350Views0likes3CommentsvCMP image upgrade
Hello, I have been tasked to updgrade the all our cVMP hosts with a new image and hotfix. I have been uploading the images to the main host by scp (-> /shared/images). This way the file gets transferred quick and easy compared to the GUI. Is there a way to do this with the vCMP hosts as well, insted of using the GUI?

I am trying to upgrade a 3600 currently running 9.4.8 to 10.1.0 using the instructions at: https://support.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/umd_make_install_9_4_x.html I created a bootable USB, plugged it into the 3600 front USB port, and rebooted from the console. I get as far as Terminal type? [vt100] and hit enter. Then it just drops into a bash prompt and sits there. The instructions at the above link say that I will be asked a series of questions to answer but none of that happens. Am I missing something? Thanks.332Views0likes3CommentsThe Image Format Wars
In the late 1990’s we experienced the browser wars between Internet Explorer and Netscape Navigator, more recently the battle has waged on between IE, Firefox, Chrome, Safari and Opera. Now be prepared for the next battle – the image format wars. Browsers are now battling for a more optimized image format with Microsoft, Google, and Mozilla all introducing new image formats, but before we go into these new image formats let’s look at why this is emerging and the history behind web based images. The most popular image formats on the web today are GIF, JPEG and PNG. The oldest image format is the GIF, introduced in 1987, although the oldest its popularity is waning in favor of image formats with more colors options and better compression algorithms like JPEG (introduced in the early 90s) and PNG (introduced in 1995) . These image formats have worked for many years so why the sudden interest in introducing new file formats, if it ain’t broke don’t fix it. Well, it’s not that the image formats are broken, but rather how they impact page performance is the issue. The size of the average web page is growing exponentially and the largest contributor to that is images. According to HttpArchive images comprise 65% of the content of a typical web page at just over 1MB in total size. This presents a huge opportunity for improving the web browsing experience. Doesn’t everybody want a faster loading web page and to use less data on their smartphones? This has lead to the search for a way to optimize images without sacrificing quality. This brings us to the introduction of new image formats and encoding algorithms that are in contention to improve the performance of images on the web. Google introduced WebP , Microsoft introduced JPEG XR in IE 9 , and Mozilla announced earlier this year a new project entitled mozjpeg. Let’s start with WebP and JPEG XR both provide significant savings when it comes to the size of images. We did some testing recently to see how much improvement can be achieved with WebP and JPEG XR. The test consisted of 417 JPEG images and 50 PNG images. The results showed that both provided substantial benefits reducing the file size by over 50%. If the results are this good, why aren’t more sites using these formats? The answer: browser compatibility. WebP only works in Chrome and Opera while JPEG XR only works in IE. If you want your users to see the benefits of these new formats you need to create 3 versions of every image, which can be time consuming. Luckily the image optimization functionality in BIG-IP Application Acceleration Manager allows an administrator to click a single check mark enabling an image to be converted to the appropriate format on a per client basis. This eliminates the need to create multiple versions of the same object and all users can benefit from the optimizations. No, wait – not all users, only clients connecting with certain IE version, Chrome and Opera will benefit from the new format types. This is where mozjpeg is looking to change the game. Mozjpeg’s goal is to improve the compressibility of JPEGs without sacrificing quality. The beauty of this project is that the file format would remain a JPEG meaning that every browser and user would be able to see the benefits of reduced image sizes. It is interesting to track the progress of this project and see who will win the image wars, in the meantime optimize the images you can for the users that you can.290Views0likes0Comments
