Problem with rewrite 301

[chms]

Hi,

I have a redirect 301 but it doesn't work and I don't know why, can you help me?

RewriteCond %{HTTP_HOST} ^www.example.com/photos/$
RewriteRule ^(.*)_(.*)\.jpg$ https://www.example.com/photos/$1/$1_$2.jpg [R=301,L]

I also have tried with the next but nothing:

RedirectMatch 301 ^photos/(.*)_(.*).jpg$ https://www.example.com/photos/$1/$1_$2.jpg

Thanks in advance.

First, you shouldn't mix RewriteRule (Mod_Rewrite) with RedirectMatch (uses Mod_Alias) as that can have unexpected results.

It helps a lot if we start off by understanding what existing files you want to change, and from what URL/filename format to what result. For example, if you have /photos/photo_name.jpg (as it appears you have) and would like to redirect those requests to /photos/photo/photo_name.jpg (as it appears you would like). With clear objectives better assistance can be offered.

A very similar situation is discussed here: [webmasterworld.com...] that may help in the meantime.

Hi not2easy,

Thanks for your response.

I have move my photos inside folders because i had a lot mixed in a folder and now I put inside a folder named like his post.

Before the photos was in https://example.com/photos/idpost_numberorder.jpg
Now are in https://example.com/photos/idpost/idpost_numberoforder.jpg

I'm going to take a look to that post.

Thanks

RewriteCond %{HTTP_HOST} ^www.example.com/photos/$

This would never match because the HTTP_HOST server variable contains the requested hostname only, not the hostname + (part of the) URL-path.

But do you have multiple domains? If not, then you don't need to check THE_HOST.

RedirectMatch 301 ^photos/(.*)_(.*).jpg$ https://www.example.com/photos/$1/$1_$2.jpg

This would never match because the RedirectMatch directive matches against the URL-path starting with a slash (unlike the mod_rewrite RewriteRule directive that omits the slash prefix in a directory context).

But, as not2easy suggests, which method you use (mod_rewrite or mod_alias) can depend on the existing directives you have in your .htaccess file.

/photos/idpost_numberorder.jpg

Ideally, you should be as specific as possible with your regex. For example, if "idpost" and/or "numberorder" are really numbers/digits, then match only digits, rather than anything.

But otherwise, it looks like you almost have it.

[chms]

Hi,

I only have a domain and "idpost" and "numberorder" are digits.

i would try something like this:

RewriteRule ^photos/(\d+)_(\d+)\.jpg$ https://www.example.com/photos/$1/$1_$2.jpg [R=301,L]

photos/(\d+)_(.\d+)\.jpg

Typo . in there? (Non-lethal typo, if so, unless this element is sometimes only one digit.)

It took a little head-scratching, but I think I see what you're fundamentally doing--dividing a bunch of existing image files into multiple directories according to category--and it makes sense.

Typo . in there?

yes it was and it's now been fixed...

Hi and thanks to everone,

this doesn't work, nothing happens:

RewriteRule ^photos/(\d+)_(\d+)\.jpg$ https://www.example.com/photos/$1/$1_$2.jpg [R=301,L]

I also I have tried with:

RewriteRule ^photos/([0-9]+)_([0-9]+)\.jpg$ https://www.example.com/photos/$1/$1_$2.jpg [R=301,L]

but it does not work either.

lucy24 you are right, I had also one folder with 500,000 photos, imposible works with it, syply list the folder was terrible, I have moved all photos to subfolders named with the id of the post, this is a real URL example:

Before -> https ://www.domain.com/photos/1171300_1.jpg
Before -> https ://www.domain.com/photos/1171300_2.jpg
...
Now -> https ://www.domain.com/photos/1171300/1171300_1.jpg
Now -> https ://www.domain.com/photos/1171300/1171300_2.jpg

I do not know what else to try.

Those two directives are equivalent and look as if they should work. Presumably, you have other mod_rewrite directives that are working?

You may have a conflict with existing directives - the order is usually important. Please include the contents of your .htaccess file so we can check.

[chms]

Hi whitespace,

Just now I was seeing that, if there was another .htaccess in folder /photos and yes, that was the problem, I've deleted it and now works.

I was making crazy because I've check al combinatios and it shoud work but nothing.

Finally I'm using:

RewriteRule ^photos/([0-9]+)_([0-9]+)\.jpg$ https://www.domain.com/photos/$1/$1_$2.jpg [R=301,L]

Also this works

RewriteRule ^photos/(\d+)_(\d+)\.jpg$ https://www.domain.com/photos/$1/$1_$2.jpg [R=301,L]

Thaks for your help

[phranque]

Did you notice which directives were in /photos/.htaccess before it was deleted?

[chms]

Yes, basically there was a redirect

RewriteCond %{HTTP_HOST} ^images.domain.com/$ 
RewriteRule ^(.*)$ https://www.domain.com/photos/$1 [R=301,L]

[lucy24]

Bingo. By default, mod_rewrite does not inherit, so the moment you have RewriteRules in more than one htaccess along the same path, the first set of RewriteRules are ignored as if they never existed.
