We sell data to our clients. Some of the data includes URLs of researched sites. We need a fast, lightweight URL redirector in PHP. Each list we maintain can include thousands of records in each list. Each URL record provided to our client will be an encoded URL. Example: the client is given the url: [login to view URL] (not real). When they click on that URL, it first hits a server and determines client ID and List ID that is encoded into the URL string.
From the client ID and List ID, the process checks the expiration date (only saved on the server). If not expired, the URL is redirected. If expired, the URL is redirected to a page with an expired message.
To keep the project simple, the process should read a CSV file on the server that maintains client ID, List ID, and expiration dates. CLIENT_ID, LIST_ID, EXP_DATE. If the datestamp of the CSV changes, the data should be reloaded.
As far as the strategy to encode URLs, we are looking for some ideas. When we send lists to our clients, we want an easy way to encode URLs before sending. We want to be able to decode the URL on the server side without having a lookup table on the server. The URL should be encoded in a way the client can't easily reverse engineer it.

Hello,
After reading you project description, I think I have a better idea that will suit your needs. Rather than having the CSV file on the server, I recommend a MySQL database. This way it is more secure than have a file just sitting on your server. In the database, we can hold the keys for each client as well as the URLs in plain text and a unique identifier for each one along the the expiration dates. I can then write you a PHP API that we can query with JavaScript or directly from a web page. The user will send their user key as well as the key for the URL they want to access. If they are allowed to access it, the API will return the plain text URL to them.
I think this is the most effective way to accomplish this avoiding have a vulnerable CSV file just sitting on your sever. I would love you help you build this as I have extensive coding skills and have done similar scripts before. Please send me a message so we can discuss more.
Thanks,
Caleb

Respected Sir,
I have a question about if the CSV changes, the data should be reloaded.
Encode will be done on the basis of list and client id, Lets say system encoded the url and data is sent to client.
Then the csv for that particular record is changed. I meant, client id or list id changes...then the url will never be decoded.
Is that fine?
Kindly clarify.
Kind Regards,

Hello there,
I am having more than five years of experience in PHP web development.
I have read your all description carefully, I am happy that I can make your project ready.
I will use md5/ or other cipher text to encrypt the URL.
and decrypt it using key which we had used.
I can complete this in next 3 days.
Let me know your quick and positive reply.
Thanks

C PLUS PLUS. Hi, I could do this for you - but since you want the server to be able to decrypt the url and not lookup a database then it would require encoding, not encryption...and perhaps something modified, or for example 10000 iterations of normal encoding scheme (base64, base58, etc)...that should be confusing enough since all the decoding is done on the server side.
Let me know if interested ! Thanks

Hi
As you suggested "to keep it simple we will use excel sheets ", I am sure that will make things complicated, its better to use a database for this kind of operation as there will be a lot of entries and searching and sorting through them in an excel file will be a mess. Please let me know if you are interested.
