Rewrite Rules

[Taffy]

Hi,

Is there any means to be able to add more Rewrite rules than seems to be possible from the GUI?  Even though the text field seems to accept limitless rules, rules at the end of the list stop functioning if the list becomes too long.

Thanks

[David]

Yes, we do.
You can use "RewriteFile" to load a file which has rewrite rules in it.
The format is
RewriteFile  /path/of/the/file


Thanks.
David

Thanks David.  Do these files have any size restrictions too?

Could be a good update for the GUI, enforce a character/line limit on the rules editor?  Could have saved me days of testing and research!

[David]

We do not set any size limit for that file and also you can combine to use "RewriteFile"/"RewriteCond" and "RewriteRule", and also there can be more than one RewriteFile.

Thanks.

Hi,

I can't seem to get this to work.  No matter where I put the file or what path I enter, the log always shows:

Error: Rewrite file [/home/user/rules/rules.txt ] can not open.

Am I missing something?  I can't find any documentation on the RewriteFile directive to check against.

Bump?

It is likely a problem with file system permission, the user that web server running as cannot read that file.
It could be directory along the path has strict permission mask.
you can try from command line

if OLS is running as nobody, you can try

sudo -u nobody cat /home/user/rules/rules.txt

also try
sudo -u nobody ls /home/user/rules/
sudo -u nobody ls /home/user

to find out which directory have permission problem.

Best regards,
George Wang

Hi George,

I've run the commands, there's no issues with permissions, I can cat the file contents as nobody.

What I have found after more testing:-

1. RewriteFile directive only works if it's the LAST directive in the GUI, otherwise I get the error about not being able to open the file.  This is no good when rules must be in a specific order.
2. I can only get it to fully work if I delete all rules from the GUI and place them in the file.

Not sure if this is the intended behaviour or not?

[David]

There were two bugs in this case.
One is the when try to load the RewriteFile with \r at the end of the file path, it will cause 'can not open' problem.
Another is when RewriteFile is in the middle of the rules, it will be mess up and cause problem.
All of these two bugs were fixed and will be in the next release.
Thanks.
David
