10. A computer program product, comprising a computer readable hardware storage device having a computer readable program code stored therein, said program code configured to be executed by a processor of a computer system to implement a method for testing multiple language versions of a browser-based application, said method comprising: said processor receiving a host language Hypertext Transfer Protocol (HTTP) request issued by a host language browser, said host language HTTP request configured to be sent to a host server address, said host language HTTP request comprising a plurality of parameter strings in a host language; and said processor generating a target language HTTP request by replacing each host parameter string of at least one host parameter string of the plurality of parameter strings in the received HTTP request with a respective target parameter string associated with a target language that differs from the host language, said generated target language HTTP request configured to be sent to a target server address associated with and different from the host server address, wherein the at least one host parameter string in the host language HTTP request comprises at least two host parameter strings, wherein a table comprises the globalization rules of correspondence between host parameter strings in the host language and corresponding target parameter strings associated with the target language, wherein one column of the table comprises a different host parameter string of the at least two host parameter strings in different rows of the table, and wherein another column of the table comprises the target parameter string corresponding to the different host parameter string in the different rows of the table.
