NimbostratusMaintenance/sorry page with image on v11.1
I have written maintenance pages in the past with ease. The examples Devcentral were very helpful. The problem with creating one now that I find are the "iFiles" introduction in v11.
The way we used to do it is this:
"when HTTP_REQUEST {
Check active members of pool, if 0 respond with Apology Page.
if { [active_members your_pool] == 0 } {
HTTP::respond 200 content {
Apology Page
We are sorry, but the site you are looking for is temporarily out of service
If you feel you have reached this page in error, please try again.
}
}
}
"
To get a logo in the html, we just had to put it in a path and call it out. With iFiles, I understand, we call it with the "HTTP::response" 200 command. Since I already use it to create the html page, it seems I cant use it again for the logo picture call. I created this iRule for the new sorry page:
"when HTTP_REQUEST {
Set global variables.
set VSPool [LB::server pool]
set logo [ifile get logo.png]
Check for active members in the associated pool and respond with html content when the pool members are less than 1
if { [active_members $VSPool] < 1 } {
HTTP::respond 200 content {

I have tried to call the "$logo" variable inside of the html as well as the "[ifile get logo.png]" command but it doesnt work. I even tried to add an "IF" statement before the html "IF" but all it does then is show the logo, no text.
ideas?
TIA

I really like the fact that you are using a switch statement && iFiles to host all of the content on your maintenance page. Great stuff.
lunitic_56137Shoot,
It looks like I didn't escape the code correctly. Sorry about that.

- lunitic_56137So I take it the iFile for index is the html code and there is an href for /f5-logo.jpg?
- nitass
yes, index is html and logo is jpeg.
- lunitic_56137ok. Thanks. I will try that.
- lunitic_56137ok, I set up the html page and it only shows the html code
El_JefeMake sure you import the iFile correctly - have a look at this - https://devcentral.f5.com/Tutorials/TechTips/tabid/63/articleType/ArticleView/articleId/1086514/v111ndashExternal-File-Access-from-iRules-via-iFiles.aspx
If you haven't already. I got mine to work with no problems.
Jeff- lunitic_56137I went according to that posting. When I go to the VS, I see the html. I am wondering what I could have missed. I imported the files, then made the iFile reference in the iFiles section under iRules. I see the code as it is in the index_html file. It just doesn't interpret as html code. it displays as text. I have done this before and it has worked fine.
- lunitic_56137Nevermind. Seems to be a problem with Firefox. IE seems to work just fine
