HTTP to HTTPS Location rewrite with custom port
Problem this snippet solves:
The SSL port is assigned in the following line:
lreplace $loc_list 2 2 [lindex [split [lindex $loc_list 2] ":"] 0]:80
change the ':80' to any required port to remove to remove any port assigned within the Location Header.
How to use this snippet:
Code :
# Rewrites the HTTP Location header in a HTTP Reponse from HTTP to HTTPS and a none standard port to the end of the hostname # e.g. Location Header 'http://www.test.com/path1/path2/index.html' will be changed to 'https://www.test.com:80/path1/path2/index.html' when HTTP_RESPONSE { if {[string tolower [HTTP::header Location]] starts_with "http://" }{ #Splits the Location Header string into a list # e.g. http://www.test.com/path1/path2/index.html = 'http:', '', 'www.test.com', 'path1', 'path2', 'index.html' set loc_list [split [HTTP::header Location] "/"] # Replaces list location 0 (first item) with 'https:' # e.g. list item 0 = 'http:' and is replaced with 'https:' lreplace $loc_list 0 0 "https:" # Appended the port number to list location 2 (the FQDN), if a port is already defined this will replaced # e.g. list item 2 = 'www.test.com:897' is replaced with 'www.test.com:80' # e.g. list item 2 = 'www2.test.com' is replaced with 'www2.test.com:80' lreplace $loc_list 2 2 [lindex [split [lindex $loc_list 2] ":"] 0]:80 # List items are joined back together with '/' inserted and set at the new HTTP Location Header # e.g. list = 'https:', '', 'www.test.com:80', 'path1', 'path2', 'index.html' becomes 'https://www.test.com:80/path1/path2/index.html' HTTP::header replace Location [join $loc_list "/"] } }

Same comment as above. What gives? Does anyone read these comments? This irule, as written, generates the errors Pavel Stoyanov pasted above. How do we fix this?

lreplace command doesn't replace any value in list but returns a new list with replaced value.
you can use this command :
set loc_list [lreplace $loc_list 0 2 https {} [lindex [split [lindex $loc_list 2] ":"] 0]:80]
or
set loc_list [lreplace $loc_list 0 2 https {} [getfield [lindex $loc_list 2] ":" 0]:80]
